I was about to go into business with a guy a few years back.
On our 1 on 1s, he was amazing, sharp, prepared, asked great questions, the whole thing.
We went to a dinner with 6-7 other people and I saw a totally different side.
The waiter came over and he wouldn't even look at him, just waved him off mid sentence while he was talking to the most senior person at the table. Did it twice.
I never moved forward after that dinner. Didn't make a big thing of it, just said I wasn't feeling the fit.
In my opinion, the way someone treats a waiter, an assistant, a person who can do nothing for them, is not a small detail.
It's actually the most reliable “data“ you'll get about what working with them will be like.
