I know the US and Canada have a strong tipping culture, where you are expected to give a tip of approximately 15% of your total bill after tax. You may even tip up to 20% in cases where you had exceptional service. In UK, no one expects you to tip because the waiters are well paid. In Malaysia, patrons hardly tip but the waiters wish they would. I never had to eat out in Nigeria so I don't know what it's like back home. I want to know from working-class Nigerians, who spend most of their day at work and therefore have to eat at restaurants, if there's a tipping culture?

Not really... except in top restaurants.

No such thing in naija. Infact, if you don't give people their complete balance after they pay their bills you are done for
