Uhm.....the app plate should be cleared BEFORE the entree comes out. Condiments such as ketchup/mustard should be on the table BEFORE the arrival of the entree. You ask abt dessert ONLY when all guests are done. This waitress was rushing the guest so obviously.
First, the woman in the stripe shirt should check her appearance and fix her shirt. Secondly, always put down a beverage nap. Thirdly, no respectable server acts this way. You can see these two women could hardly keep from laughing bc of how ridiculous this video is.
