@freemo I may be too Dutch to tip at all, ever. I dunno.
Back in Berlin we tipped 1 euro cent because of the terrible service and food we received.
In Eastern Europe I've seen bars and restaurants charging a 10% service fee, which usually is not allowed by law, and is a tip by another name.
@ligthert @freemo if it's for food service and they did a good job, tip. If it's delivery at least toss a couple of bucks on it, only a very bad delivery should have no tip. People wear and tear their cars, it takes an exorbitant amount of time with traffic, parking and waiting for orders, and gas is expensive. Delivery work sucks. Tip your delivery drivers, especially if they go above and beyond.
USA tipping and Dutch tipping arent really comparable. In the netherlands they are paid a fair wage. Obviously tipping helps, but they are paid a living wage, tipping is what it should be for, extra as a thank you for excellent service. It isnt needed to ensure they get fair pay.
That said, if you can afford it it is certainly nice to be generous with people.
