I am currently working a food service position that is very fast paced. We have long stretches of break-neck panic and then a few minutes of downtime. It's a small store and there isn't really a place where we can eat AND get all our stuff together for the next rush. Therefore, I sometimes have customers walk in while I have my mouth horked full of sandwich or taco or whatever. I'm always super embarrassed when this happens but I do have to eat sometime. Food service workers and customers alike, how do you feel about eating in front of the customers? Gauche or forgivable?
