Could not wearing a mask also be a civil crime? Could I be sued by some nut that managed to get video of me going into a grocery store without a mask? Who win

Could not wearing a mask also be a civil crime? Could I be sued by some nut that managed to get video of me going into a grocery store without a mask? Who wins? Would people be likely to settle to avoid the hassle despite being unable to prove I infected them? Has this already happened?
