I haven't hade many negative encounters. The two most memorable ones are as follows:

1) A man in a grocery store asked me if I had lost the bet. I replied that I actually won the bet and got a nice kilt out of the deal. He just nodded, said "Okay," and went on his way.

2) A man in across the bar muttered that he had never seen a man in a skirt before. He said it kind of offside to his buddies, but he seemed to say it loud enough that he wanted me to hear. I walked up to him, not knowing what I was going to do or say. I noticed a couple women among his circle of friends as I walked towards him. I grabbed one of the women and planted a nice kiss on her lips, then winked at the man, turned around, and left the bar (thinking to myself, I've either had the final word, or I've just started a fight).
Fortunately, there was no fight.
