When you go to a bar a waiter/waitress will take you to your seat. She will then take your order and expect a tip of approximately 10-15% when you pay for your drinks.

In England I went to the bar, bought my own drinks, and paid no tip...

Even if you go to the bar to order your own drinks, many bar tenders still expect a tip in Canada.

I think they are too close to USA...

Greedy people.
