There's a revolution brewing against tipping at restaurants.

Andrew Freeman, founder and head of the hospitality communications agency, Andrew Freeman & Co, issues annual reports about the latest trends in dining and restaurants, and he says some restaurants are thinking about ditching tips and just charging a service fee.

Some people say that tipping is bad for servers who are probably getting paid less than minimum wage, and bad for customers who aren't getting better service.

Freeman says a lot of European restaurants have already replaced tips with a service fee, and he says upscale American restaurants may follow suit.
