You know what I hate? I'm at a restaurant, eating food, and the server asks if they can take my plate away.
Worst way: "Are you still working on that?" Working on that?! Yes, I'm still eating, and thanks for effectively making me feel like a piggy for still 'working on that'.
Let me eat my food in peace! Quit trying to take my plate away before I'm done.
Thank you. I feel better now.
