It's a bit hypocritical IMO to say you'd never reach into an open bag, but you'd grab a fresh bag and open it and have others reach in after you. Perhaps people don't want sanitizer or anitibacterial wipe residue on their chips.
And as I said before, I'm "immunocompromised" too. Each to their own.
I never said I would never reach into an open bag. It just makes me leary and I would find a way to get my kids the chips while avoiding most of the germs and at the same time avoid getting other chips germy.
Most don't care and would not even be bothered by it, so why would they care what I do? If I want to reach in the back or grab a new bag, it's no skin off anyone else's nose IMO. Others can do the same if they wish or just reach in and go for it. Which is what most would do and what I would do if I wasn't compromised. And that's okay. We all do what we need to do. No need to make is sound like am a selfish Bit## because I have to be careful.
