Tipping generally only happens in america. The rest of the worlds working staff dont expect handouts as a right and wouldnt take a job without a standard min wage.
Its like a taxi driver expects a tip after you pay him a fee. Thats rediculos. Waitresses perhaps deserve a tip more imo but they shouldnt expect it. If someone blatently asked me for a tip i'd say get a job that pays
The mixture of ignorance and arrogance in your response is pretty impressive. Congratulations.
Tipping, while approached differently by different cultures, is very much an international phenom. Wiki lists the tipping customs for 46 countries not including the US.
Tips aren't hand-outs, they're gratuities for services rendered. Bartenders and waitresses aren't standing out on the street asking for free money. They're working inside bars and restaurants serving food and drinks to you and your family.
The overwhelming majority of restaurants in America do not pay their tipped employees the national minimum wage. Depending on location some waitresses may only make $2.75 per hour. Many of them work extra hours/days off the clock or even forego full-time employment status while working 50-60 hour weeks. The extra money that they earn in tips makes these sacrifices worth while and keeps many restaurants (which would otherwise fail) in business.
I'm too lazy to look it up but I believe there is a standard minimum wage for tipped employees. It's just not as much as the federal and is regulated on a state by state basis.
Don't worry about tipping people though, who needs them?
