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]
Also illegal. It's called bait and switch. Advertise one price, provide the service, then change the price. What if you went to get $50 in gas, and after you put the nozzle back the price suddenly changed to $59. Unless there's a very visible sign saying it would happen before you started pumping, it's illegal.
