My best friend is getting married soon. I am her maid of honor. She is having prime rib and other items as her meal buffet style. The caterer is dropping off the food and then leaving. They will return 5 hours later to pick up their containers and dishes. After the guests eat they are expected to take all of their plates (salad, main, and dessert) into the kitchen to have cleaned for the caterer. She only has one bartender and thinks that the bartender will refill sodas, teas, lemonades for people along with mixing drinks. She has 290 guests that RSVP'd. Am I crazy to think that this is poor etiquette?
