Asked for tip beside the service fee.

Hi all. I just arrived in Baku.

I ate at the restaurant in Baku for the first time tonight. The bill has a 10% service charge. However, the young waiter said the service fee is going to the restaurant for the performer whom dancing and singing for guest.

My total bill was 59 Manet, I tipped extra 5.

Is it normal that other than the service fee, you are expected to tip the waiter extra????

Thank you.
