Slowly the "Service charge" made its way from the French side, where it was common practise. I was NEVER a fan of that and to my point neither does anyone that dines on the Dutch side! IMHO, if the restaurant owners got together and discontinued this practise the staff would make a lot more money! Yeah sure now and then one of the Europeans would stiff a waiter, but overall they would do better!! They shot themselves in the foot with this. And why not ask if the 15% is tacked on. I got taken once. Double tipped not knowing, when approached the manager, he said the restaurant is now close, I can buy you a drink. As if that cured the problem! Ask, it doesn't hurt! If the service and experience is that good, I leave some extra cash! If not, I'm walking!
