I go to my hairdresser's house for my appointment and get a cut and blow dry in her kitchen. Kitchen has the back door to outside. Hairdresser smokes and so does her partner. Partner not there all the time but when he is he often sits at the dining table smoking. Hairdresser sometimes smokes during appointment but when she does she opens the back door. AIBU to think that you shouldn't smoke when you run your business from your home and have clients in getting a service? My sister thinks I should get over it as I'm choosing to go to the hairdresser's house and it's her home and she can do what she wants.
So:
IABU - hairdresser can do what she wants in her own home despite having clients in at the time
IANBU - hairdresser should treat kitchen as a place of work during appointment times and not smoke or allow her partner to smoke
