Us foreigners like me an Australian , or British, Europeans & New Zealanders who may visit the USA for a Holiday are not used to tipping.
I know Tipping from customers makes up quite a bit of a workers wages in the USA.
So some basic questions about Tipping in the USA.
How much do you normally tip someone.?
Do you have to Tip ?
If you have 2 people serving you.. do you tip both ?
Do wait staff in Canada expect Tips as well. ?
