During Covid there was this toktok(??) trend to lick food and put it back on the shelves in stores

People were jailed for that, iirc, because it was tampering with food. Rightfully so, if you ask me. If I get sick from bacterias.on your body, it might potentially even kill me. You think that is okay? There is a good reason why we are so careful with food, not to mention that it's just fucking disrespectful and gross.
