Went to a restaurant in LA today and when I got the check I noticed that it was a bit higher than it should be. Then I noticed this 18% service charge. So... We, as customers, need to help pay for their servers instead of the owners paying their servers a living wage. And on top of that they have suggested tip. I called bs on this. I will bet you that the servers do not see a dime of this 18% service charge. [deleted a word so it wasn't a grammatical horror to read]
People look at the menu, decide the prices are reasonable and eat. They then get hit with an 18% service charge and (in the US) a 20% tip on top.
The restaurant could increase their prices by 18%, but then people would decide to eat elsewhere. Of course they'll do that anyway after being hit with all the charges, but the owner thinks it's worth it to get the custom once.
