I know this varies country to country so I'm just wondering what your thoughts are about tipping. For example I'm from America - here it is customary to tip because the waiter/waitress makes basically all of their income on tips. I know this isn't the case in other countries though. In my part of town (probably much like most of America) it's not only customary to tip; it's basically essential, if you don't leave a tip that means you had terrible service - in fact your just as likely to not pay your bil. Personally I tip 20% of the bill, 25% for any kind of good service and possibly more for exceptional service. I think this is a bit higher than the average - and I hope it is. I understand the people serving me are working well below minimum wage and this is their whole income. So what's is like in your area? Is tipping customary or even mandatory? What do you tip on average?
