[Gary L]

There was a surgery where there was a guy outside stopping people going in and giving them a spray of the hands, a tie on face mask, and a pair of gloves to put on.

The procedure was he would stop them. put a fresh mask and gloves on himself. fully kit them out before entry, and throw his mask and gloves in the pedal bin.
when they came out he would again put on a fresh pair of gloves and mask and get them to put theirs in the bin. wait till they were a few feet away from him before he discarded his mask and gloves in the bin.

this went on and on till we got bored of watching.
