I once sponsored a man who was a professional barman.When he made amends to his ex employer they offered him his old job back,he took the job and has been sober for some years now.But......He was an active AA member who had worked the steps and was on firm spiritual ground.His main trouble came from dishonesty,they give the customer free drinks and big pours to enhance the tip they receive.He had to modify that behaviour as it started to bother his conscience.
