Great idea. Think I have built up enough resentment towards my grocery store to do that.
I was only challenged once at the store, I never wear a mask. Just about every visit I am the only one in the store without one. It was a new greeter. I said - I have a medical exemption - and she said - ok you’re fine and folded like a cheap suit. By law they cannot ask you about your exemption according to the American Disabilities Act.
Ok, let’s both try that our next time out. Go in, gasping, coughing...no mask.... and give them a paper list of stuff.
The $200 list... “hey, shop wisely please, I only got about $100 bucks ok? If you need to ask about brands...cough...cough...just come out to the white truck in the lot......God Bless you man!”
