Is it normal that waiters touch your food with their bare fingers?

I had vacation in Turkey and something weird happened to me. After ordering at a restaurant (it wasn't a cheap one) and eating a first plate of dürum bread, I thought they served a 2nd plate of bread and I waited for the rest of the meal, then a waiter GRABBED and lifted one of the breads to show me that there was kebab meat inside.
