Bosnian Restaurants in Ljubljana

Ok, the food is authentic Bosnian, but the prices are rather steep and the couple who own the restaurant need to go on a customer care course! The restaurant is usually empty, which kind of gives you a clue, but we thought we'd give it a try on one of the nights with live music. We bought the musicians a drink and the owners took the drinks from their hands and threw them down the sink and told us we should have ordered more food! Dont come here for a pleasant evening.

What the hell's going on here...should I be offended?
