I currently have a lovely but very smelly plumber fitting a new shower, he has been here less than 20 mins and unfortunately, my house now smells of a mixture of BO & stale smoke so I have been going around the house opening windows pretending to be hot.
The plumber has now come down and asked if I could shut the windows as he is feeling chilly, 
So my AIBU is, do I put up with the smell or just say no and keep the windows open and ask if he can pop on the jumper I can see in his van?
I don't want to be rude to him or upset him but he really does pong quite a bit
