In our place, we have those events permonth in the restaurant. We first sanitized the employee then he wears a hair net, and a plastic cap. Plus we made sure to change the nacho hat every 2 hours, preserve it (or just straight up eat it if theres a few left)
Since even though we clean the ceilings daily, there'll be bound to be people who double dips or even pick up a chip with their dirty, unwelcomed hands.

Im sorry but that nacho hat is pretty disgusting if you’re gonna eat it. I just imagine a customer snapping to eat some but the employee has been wearing it all day so all that sweat and bacteria (and he had long hair too!) spreading around the chips and ughhhh
