I've got a solution... Just come to my restaurant and let me mix you a drink! I wash my hands ALOT annnnd I'm the only one allowed in the bar so NOBODY touches my stuff! They know there would be hell to pay if they did! Plus side is most bars have a sink handy where the bartender washes glasses ( mine has 3 one just for handwashing!!!) so even if it's not intentional their hands end up in soapy water periodically lol
