>>9890319Tipping as a mandatory thing is very American and comes from practices established during the great depression that just sort of became an American tradition.
In fact, before it became an ingrained thing, tipping was seen as being in poor taste, akin to bribing a waiter to get better service.
>>9888001That said if you're in America and you don't tip your waiter, then you're being a cunt. Dining in America is cheaper than it would otherwise be in part because tipping is expected. If you don't believe in tipping then push for a change, not paying tip isn't promoting change it's just you being a cheap bastard.
