Yah that’s what Milkfarm was doing (for Takeout Cheese & Charcuterie & Wines when we went a few weeks back). They posted a sign and explanation saying that they calculated if they swapped out gloves after every transaction (or if they had to touch the register for payment and then the customer wanted something else), they estimated they’d blow through 500 pairs of gloves per day. So for the environment and more efficiency they wash their hands instead.
We saw them (open store area) diligently washing their hands, then helping the next customer, and if they touched the register, they immediately went to wash their hands again, etc.
