So you gave "Miss Ugly" a laugh in her otherwise dull and boring shift at work.
You didn't mention her giving you a hard time, so I would not even think about it. You probably made the rest of her shift quite pleasant!
As I have been out and about with you in heels, you are always discreet in your choice of outfit and your heeling always looks appropriate..... Even if you are spotted, I really don't think you are going to get abuse!!
But good on you anyway, You are really getting out and about in heels at the moment.
