Doesn’t annoy me, mostly because people need their money. You need to provide so much, yet you get so little, so a lot of people don’t see the cold or illness as a reason to not make money, if they think they can hack it.
Perhaps easier for me to say, since I seem to be nearly immunized to the common cold. Every time there’s a wave of sickness at work, I get off scot free, or with some minor sinus problems while everyone else is dying from the plague for like two weeks. Although as a kid, I got sick all the time with nasty colds and flues. Did my fucking part.
I see your point though, it can be frustrating, although I don’t find it necessarily rude, per se. People gotta do what them peeps gotta do, although I admit, would be nice if some thought of the consequences they’re creating.
