I get that you don’t want to sell clothes that fit me. While it would be fabulous for you not to send a de facto message that I don’t (or shouldn’t) exist, you’re well within your rights to sell whatever items of clothing you like in whichever sizes you please.
However.
It’s a little much to ask me to support your business, even if the new store in town will have snacks at its grand opening.
Furthermore.
While I’m not generally in favor of telling people how to feel, I’m going to make an exception one time because this is sort of the point of the whole letter.
Because.
You should not feel surprised when I tell you (or your new store representative) that I have no wish to support a company who has taken no steps to include me.
You get to make choices, certainly. But decisions have consequences, and that one was foreseeable.
