Maybe, maybe not, but I definitely wouldn't change gloves every five minutes. Squirting some hand sanitizer after every client in retail doesn't seem as onerous. And definitely if my nose itches, I would rather squirt some hand sanitizer, clean my hands, and scratch it; rather than take off my gloves, scratch my nose, than put on new gloves.
I would have to change gloves every time I want to touch my face. And if I am to avoid spreading between customers, I would have to change my gloves after every customer (or wash/sanitize my hands).
