You could start by telling off any idiot that wears a mask. Especially if they are doing it to virtue signal.

You don't need to be rude. A simple 'sorry I don't speak to people who wear masks' to the Karen who loudly announces she is putting on her mask to pump gas or whatever does wonders.

I've quit tipping any delivery drivers that show up with masks, or who do dumbass shit like drop my food in the snow for 'contactless delivery'. I've tripled my tips for those with a smile on their faces who hand me my food in a civilized manner.

As for vaccines, I wouldn't worry to much. It'll be at least a year before there are enough vacced people for it to be an issue. And there are enough regular normal non-RNA vaccines in the pipeline that you'll be able to choose something as harmless as the flu vaccine.

I am far more worried about the world turning into a non-gendered masked version of the middle-east than I am about vaccines.
