Had a tradesman in this morning for about an hour. I realised after he'd been here for about 5 minutes that he had a streaming cold! In normal times this would have been annoying but acceptable, but at the moment I feel he should at least have checked before coming if it was ok. If he's managed to catch a cold then what else has he got?? We are in an area of intervention as well... I have anxiety so don't always see things rationally - AIBU about this?
