bachian saidI don't tip richer people. Earnings in Brazil (and exchange rates) are such that American / European waiters are probably making more money than many Brazilian tourists.
Then it is ridiculous of you to travel to the united states and eat in a restuarant. It's offensive to the wait staff. Even some tip is ebtter than no tip. Because they may earn, voerall, more than you, but their living expenses are probably higher as well.
And waitstaff make like shit all. I worked in a restaurant during the olympics in downtown vancouver. I nearly killed some of the people. It was ina hotel, so we had a lot of foreign people comming. In russia, apaprently, it's not common to tip, as we were told. About a week in we started autograt, much to the chagrin of our regular guests. But we were earning less in tips than a normal week, because foreign people encer tip.
I'm sorry, but you cannot expect me to bust my ass, bringing you everything, from a new fork to another dirnk, ata table of 12, while I juggle 6 other tables, and then not get mad when you don't leave a tip. It's ridiculous. Servers don't get raises, orbonuses, or even enough wage to pay basic bills, and they dont get paid this ebcause tips are where it comes in.
