I live in California. In California, servers (waiters/waitresses) get paid minimum wage and on top of that they get paid tips.
If a server is working three tables an hour, he/she has the potential to make a lot of money off tips.
Let's say the server gets a measly 4 dollar tip from each of the three tables he/she serves in that hour. That's 12 dollars on top of 8 dollars. 20 USD per hour for server isn't bad money at all. Sure, the server will have slow days, but please, I don't need to hear you say that 15 percent is not enough.
This Saturday I'm going to an expensive steak restaurant. The total bill will likely exceed 150 USD. You want me to pay 20 percent? The server will be getting paid the minimum wage plus the tips. Now some people think the restaurant owner garnishes tips. But some don't for tax reasons. They don't report the full tip count so they can take more money home, tax free.
15 percent of 150 USD is 22.50.
If the server only serves my table for one hour, he/she is going to make 22.50 off of me plus 8 dollars wages.
That's more money than my sister makes per hour working at a law firm. I guarantee the server will be managing at least two other tables in that hour.
From tips alone, he/she is going to be making a lot of money that I frankly do not think he/she deserves. I could do without the false smiles and the cheery attitude. The food alone is amazing. I don't need them to be twerking around the table to get that money.
Bottom line, my tip percentage varies based on the price of the meal. If it's a relatively cheaper bill, like 35 to 60 bucks, I'll tip 15 percent. If it's more than 60 bucks but less than 100, I'll probably tip 12 percent. If it's more than 100 USD, I'm tipping 10 percent.
I will NEVER tip 20 percent. Whoever thinks 20 percent is the new standard needs to be out changing the system rather than arguing for us to pay that ridiculous fee.
It's not a matter of, "Oh, if you can't afford it, don't eat out." I can afford it. That's beside the point.
