Obviously, if it was an ongoing problem like body odour or halitosis that would be different.
Went to my next door neighbours house last night to give a birthday card. Neighbour is very elderly and requires care. She's also a bit deaf, so I leaned over to speak to her as one of her carers also leaned over. Carer pulls a face and says something like "ugh, have you been eating garlic?"
I hadn't, as it happens, but I do have just a touch of hayfever which is probably blocking the back of my mouth a bit. But no one else has complained!
AIBU to think this was extremely bad manners?! It's made me quite cross!
