All the SA's Ive met have been courteous to me. I have only had one refer to me as sir, and I think she was nervous, as she said was new on the job. I was probably her first tranny customer(and I do tend to be more intimidating than a barrel of ferrets). As said most of them are probably happy to be in business and make a sale. A few have engaged in small talk, but all have been professional. Except for the male SA who rolled his eyes when I said "Im not sure which boots I want but I will know them when I see them", I swear he whispered "women" as he walked away.
