Are you all serious?

I have never experienced a "false wait" myself, but in case of being asked to wait while there are clearly empty tables, I would leave immediately. This whole "wait to be seated" thing is very American. In Europe, it's common at higher-end places that operate on a by-reservation only basis. In a low-to-mid range place, you would just look for an empty table and sit down by yourself (maybe making eye contact with a waiter to check if that particularly table is free).

This doesn't mean service in Europe is universally better - long waits before being served are not uncommon, but restaurants would make you sit down, bring you drinks, maybe some bread and snacks, and take your food order. So at least you can wait in comfort, plus you cannot just get up and leave because they might have already started preparing your food.
