People were wearing surgical masks, and even after I explained that those masks leak like a sieve and are pointless for mold spores people still wore them.

I have to wear a full gasmask & faceshield to deal with pollen. The idea that people think that they are protected from mold (which is probably more dangerous and lethal to them than Covid) with a fucking N95 mask means they should be immediately escorted off the premises for their own safety.
