Maybe so, but presumably you don't tip your doctor regardless of how well they do their job.

I don't tip a doctor with money (because it is strictly forbidden in Austria), but it's not unusual to give him a small gift (fine chocolate and similar things) and I would definitely do that after an operation if I had one.
