I thought it was odd the first time I was charged for a bucket of ice at a restaurant here in Thailand. But now it appears normal.
I wonder when restaurants in the west will start charging for restroom use? How about charging for paper napkins or maybe a rental charge on utensils?
Condiments should be like others items such as employee wages, overhead, cooking oil, salt/pepper, etc...... all rolled into the cost of the product/service. Itemizing it is just asking for trouble.
