Turkey is a tipping culture and I understand it's standard to tip 10-15% on sit-down restaurant meals. However, many nicer places also apply an automatic 10% service charge to your bill. Are you still supposed to tip on top of this?
I've been topping off the bill with cash to make it roughly 15%, which staff seem happy with since it has on a number of occasions led to complimentary bonus desserts landing on our table, but I'm curious if this is just Turkish hospitality or us being excessively generous. We're talking 50 TL/2 EUR on a bill of 1000-something/40-50 EUR for 4, and these are "regular" restaurants, not Sultanahmet tourist traps.
