One user described being frustrated by people trying to help unload their tray: "I work at an upscale cocktail lounge. Please DO NOT take your cocktail off the tray while I'm setting down someone else's drink because you think you're 'helping'. I am balancing a tray of 5 cocktails on one hand. You will throw off the balance and I will drop ALL your cocktails." Let your server do their job, and avoid catastrophe.
