My advice to him would be that not Al women are gold. As for the interaction, my suggestion to him would be to ask the woman first. I am interested in getting you a cab/Uber so you can get home safe. Would that be ok?
If she was abusive and short to him, then he should have just mailed it back to her and kept a tracking number.
If she was truly nasty a great response back would be ... You are right I may not be the prettiest on the outside, but it grossly better then your insides. Have a nice life and may you meet the nice guys at your level.
Gentlemen also have boundaries and when they are crossed civically, then response are aok.
