I never tip. When I pay so much for my hotel room, or restaurant meal, I don't expect to have to pay more than what the bill will be.
I pay that money to get served, otherwise I go to a kosher equivalent of Mc Donalds.
If you think of it, if a housekeeper gets $ 5 per day per room and makes 20-30 rooms a day, that would soon mean a $ 100 extra, not bad.
Soon, we will have to tip flight attendants, cashiers, ....
There are so many people who work hard for their money, and don't get a tip either.
Tipping should be abolished!
