If a food place ran out of something you like would you still continue with ordering or just be like nevermind and move on?

Not really but depends on the place. A wing place by my house I used to order from, I don't bother getting from there anymore at all because they got rid of just about everything I liked from there. Last time I ordered from there, I got told they don't have this or that anymore after trying to order 3 different things after being constantly told that same answer, so I got annoyed and asked "Is there anything that you do have?"

Depends on the place, how hungry I'd be and what else they would have to offer.

Tough one

Probably not

If they don’t have onion bagel I pivot to everything bagel

Move on. Not important.

I'd move on

Try something different off the menu
