Yeah, it's relative. Bartenders can make decent money in America, but I'm guessing it's a modest salary in most of the EU.

I just moved to the Netherlands and have no qualms with the service in most restaurants. At least in my region (Brabant/Limburg) everyone is very nice. If I had to complain about anything, it would be sitting for 20 minutes after the party is finished eating, waiting for someone to clear the table. The service has been excellent and I enjoy paying the price on the receipt with zero surprises!
