Theses are the top 3 things I do when this happens:
3. Nod and smile. The waiter is long gone before I find my voice to speak, though. This is probably due to the fact that there are french fries lodged in my throat at the time. Good thing I'm not prone to choking.
2. Conveniently vanish to the bathroom to avoid the question. He's already asking me if the food's okay. Does he really have to ask me if I'm choking?
1. Nod like an idiot with food in my mouth and shoot him/her a thumbs up. Hey, it's the best I can do, under the circumstances.
And yes, I know they're supposed to use that time to ask you if you need anything else, check your drink levels, etc., but the whole reason I try to avoid the question is because I'm socially awkward, remember? So, if I'm too shy to even answer your question, do you think I'm really going to speak up and ask for some Heimlich for my french fries?
Then again, maybe I'm just over-thinking the situation.
Or, maybe I just shouldn't leave my house anymore.
