All foreigners pay attention closely. In the US, tipping is so heavily ingrained in our culture that the federal government considers tipping to be a legitimate form of income for people in certain jobs. Therefore, special rules apply when it comes to employees who earn tips. Specifically, they allow restaurants to pay a wage much lower than the standard minimum wage because it is assumed that the tip is the primary form of income for the server. The only reason they are paid any wage at all is because then they can make the server declare a percentage of their sales as income, and the paycheck is used to cover their taxes. It's not uncommon for a server to receive a paycheck for $1 or $2. Many don't get one at all. They just get a check stub that shows their pay and deductions. And whether you get tipped or not, you will pay taxes based on a percentage of your sales. So when you get stiffed, not only do you not make money, you actually lose it. I didn't make the rules, I'm just saying this is how it works.
We can argue about which role is harder but to be honest, you're comparing apples to oranges. The BOH staff have to deal with the physical demands of being in a hot kitchen. The FOH staff have to deal with constant mental abuse from the general public. It's a hell of a mental toll. When you're BOH, you get paid from the moment you clock in and your paycheck arrives every week or two. Your evaluations are done constantly, but nothing is usually said unless you really fuck up. When you're a server, every person you speak with is evaluating you, and their evaluation is based on a number of factors that are outside your control. I was a server for 7 or 8 years in several different places. I maybe got stiffed 20 or 30 times over the course of those 7 or 8 years, so that's not bad. OTOH, shitty tips were an almost daily event. And every shitty tip is like having someone say "fuck you" right to your face, and not jokingly. How many people go to work with the expectation that 3-4 people will them "fuck you" in a hostile manner each and every time they clock in? In all honesty, damn few. Like I said, BOH staff have their own shit to deal with. Brutal heat is the number one issue. And then when they get slammed, they've got to endure the physical heat, while keeping everything straight. It's not easy. But neither are the constant evaluations being done by customers who are pissed off because it rained today and they're on vacation (and they will take that shit out on you.) When you're BOH, your value remains fairly constant. When you're up front at the bar or serving tables, your value is constantly questioned and assessed, even when you know you're damn good at what you do.
But the point isn't about the validity of the practice of tipping or the sense of entitlement of the servers. It's about some bitch who went out and decided to blow $140 on a meal, and then declined to tip, citing that she's a single parent as her excuse. If it's a matter of affordability, maybe she shouldn't be eating out. I would see this shit a lot, especially when I lived in Myrtle Beach where they had a lot of retirees. The mother fuckers would come in and talk about "I live on a fixed income." Yeah bitch, so do I. So do the motherfuckers who work on a salaried basis. So do most motherfuckers who are classified as wage earners.
Eating out at a sit down place is a luxury. But you've got a portion of the general public who thinks it's a right. The next time you think your server doesn't work hard, keep in mind, they're the ones who have to deal with the asshole who thinks this way.
Ome more thing, a lot of servers are fucking liars when it comes to the amount they make. Every place always has a bullshitter who claims to be making $20-$30 or more on every table that comes in. And it's just bullshit. The reason they appear to do so well is because for them, much of their income is not taxed, and every day is payday. But even that's changing thanks to credit/debit/ATM cards. It used to be that you'd hold all of the money you made until you cashed out at the end of the night. Your credit card tips were deducted from the cash you had to turn in at the end of the night. Nowadays, with so many people paying for everything with plastic, and virtually no cash, many restaurants are beginning to hold the credit card tips until payday. That fucking blows because most servers are accustomed to living like low rent drug dealers, and when your tips are held like that, you then get to pay the full amount of income tax on most or all of your income. So the notion of servers making boatloads of cash never really existed, and what did exist is quickly disappearing.
