How Dare You Need To Eat!

This is during the mask mandate. I’m a cashier and I notice I start to get a bit shaky and hungry. I buy chips to eat while I do not have customers in my line. I’m eating and have my mask down while I do, because I can’t eat through a mask. A male customer comes up and shoves the large “please wear a mask” sign into my face and walks off. About ten minutes later:

Manager: “I just had a customer complain that you weren’t wearing your mask.”

Me: “Did they mention I was eating? You can check the cameras. My blood sugar dropped.”

Manager: “He did. You’re not in any trouble at all. Just giving a heads-up it happened, and he walked out saying he’s never shopping here again.” *Walks away*

How much of a jerk do you have to be over someone eating potato chips for their blood sugar and complain I wasn’t wearing a mask at the time? Sorry I don’t put holes in my mask that’s meant to protect me to eat or drink.
