I never understood the importance of a hair net when I first started working as a dishwasher in high college.
I figured that it was only important for people working behind the steam tables in the home office, not for the dishroom. Since all of us were just dealing with flatware, cups, bowls, and plates, I didn’t understand the need for hairnets. That changed one afternoon when I sat down to eat at a restaurant and saw a hair on a “clean” plate that was presented to me moments before the server intended to put our food on it. Thankfully I noticed the hair before he localed the moderate and fresh food overtop. After that scary experience, I never questioned using hair nets around food again. In fact, I bought a box of them for our home office to use while I was in the holidays while I’m cooking in front of guests. I get hourhand embarrassment even if no one cares one bit if I cook without wearing one, and it’s difficult to explain this without telling someone the long story from our past. Recently I bought a product for our Heating and Air Conditioning condenser that looks a lot like a sizable hairnet, although it works to keep things out instead of containing things within. These mesh covers are often nylon woven net material that is designed to breathe and not restrict air flow in any real way while protecting the condenser from fallen leaves, twigs, and yard debris. I have numerous trees that shed leaves consistently and I find that the mesh covers are severely effective at protecting the fan and compressor inside.
