When I worked at subway… Fuck me 10 years ago this month…
We pulled them nipples and the inserts off every night and rinsed them in hot water, then left em overnight in sanitizer solution, and I (being 6’4") had to clean the ice holder every 2 weeks to a month, never got told bad in there thanks to that
There was a picture our boss would show you of what happens when you don’t that convinced everybody to clean it religiously. We got free drinks from the machine, after all, we’d only be killing ourselves faster with that shit being dirty
