If you're changing to something that needs a glove change that often, than you're probably screwing up somewhere. You take money or wipe off counters or handle raw meat, you need to change gloves.
But washing your hands after you take off gloves, before putting another pair of gloves on?
I disagree with her testing methods and also, I'm not (nor are most people?) Using one sponge to clean my counters and then using that same one to wash my dishes.
You mean the ordering and serving guy that hands over your ice cream cone with no gloves?
I'm kind of a germaphobe and am big on washing hands, but if I were a mcdonalds employee, there's just no way I'd have gloves on to put out the hamburger patties then take the gloves off, and wash my hands, then put another set of gloves on to do other food prep stuff.
I'm not washing my hands between every glove swap. You don and doff your gloves correctly there's no reason to.
No worries for pesticides or water use, as well.
