Yuck! I was at an event that only offered a shrimp dish and a vegetarian option that was not appealing. I called the day before and asked to purchase a second meal for myself. I was told someone would get back to me, but they didn't. I politely declined the shrimp dish and the waiter raised his voice to me stating that I had not ordered the vegetarian option. I asked if I could just get a chicken breast or something and he never came back. The shrimp dish was beautifully plated but I noticed my dining partners all sent back full plates. Not for me I guess...
