Can I just get your signature right here please, Sir

I went to the bank today to make sure there was enough money in my account because my cable bill will be withdrawn tomorrow. I had to make a deposit for Teri's share and then sign a slip. I was wearing a winter hat and my winter coat. Then the lady called me Sir. She knew my name, saw me take my wallet out of my purse, and then called me SIR.

Do I really look like a man? Or a feminin man who carries a purse and who is called, Amber Alice Geddes?
