Yeah, I know a few white collar workers bartending or in a kitchen, one weekday night or so, but they had a lot of experience with the service industry before they got a white collar job, and worked in lower paying business side and non tech engineering jobs where the extra money was a little more appreciated, if not their main reason for being there. (The bartender wanted “forced” socialization and the cook was a food enthusiast who wanted to keep his skills sharp). I’m not saying a “techie” wouldn’t or couldn’t do it, but if they’ve never done it before they don’t know if they’re the type of person who would be burnt out by it or rejuvenated.
