I keep seeing posts online about if you can't afford to tip don't eat out, I know this is mainly aimed at America, however it seems people think tipping is mandatory and I don't understand, I don't have an issue with tipping but expecting someone to pay an extra £10 on top of a £50 bill is abit extreme, is it just me who feels this way? I know wait staff don't make a lot in America but shouldn't that be the employers issue?
