Ah our most favorite patron of all times! We affectionately refer to him as "Mr. Sir" as he comes in and always calls us "sir." I don't mean he calls all the men here "sir" and all the women "ma'am". No...he calls EVERYONE "sir". When asked why, his response was, "I was in the military. I learned to show respect." When told that this was disrespecting (and annoying) us, he replied, "This is America. As long as I am not being offensive, I can call you anything I want."
