Personally, I think she was out of line. Asking once, fine. Asking twice? It would bother me and shows she doesn't trust me. If the scents bother her that much than she needs to do quick drop off and pick ups or find a scent free dc.

I myself am scent sensitive (just get headaches) but can't imagine asking someone to not use scents in their own home!!! In this case, your home is a business she utilizes, if it's not matching her needs she needs to find another business, not expect you to change it for her. Self entitlement...expect ing you to change instead of fixing the problem herself.

I find it hard to believe her though if she stays 20 mins chatting....
