I'm not going to give a lady something free because her husband is disabled
Why don't you want give them something free?
I'm not a charity. I'm a place of business.
Very true! Being disabled doesn't mean you get to seek sympathy for freebies. Otherwise, if you give away stuff to every disable person you will go out of business!
I don't even think her husband is really disabled. She is trying to make me feel bad.
Maybe you are right so your decision is right to not give her any free stuff. Probably she's trying to con you.
