Had lunch with two mainland guests. Wanted them to experience dim sum, but our usual place was closed that day for a private event. The Dim Sum was good, food came to the table quickly, and we enjoyed everything we had. The service problem was that I misunderstood how to order. Rather than the usual carts, you ordered on a form they provided. I thought we were ordering pieces for each choice, but we were ordering baskets, so I marked the form on many items a 3 rather than a 1. When the server came, she loudly pointed out my mistake in front of my guests and the other diners saying I don't know what I'm doing to order 27 baskets of food. I was really embarrassed in front of my guests. It could have been handled much more delicately, I don't think I will bring guests there again despite the good food.
