I was in a heavy metal pub in Belgium, wearing my black kilt, with some friends and was my time to get the beers. I went to the bar and a woman, around 40, say something to me in dutch, I replayed that i do not speak ducth. She make a signal to me to turn around. So I did. I was expecting her to look at the pleats or something like that. To my surprise I felt her hand in my butt, grab the textile then pushing... She felt my underwear and looked at me desapointed... :S I was surprised, but in the end I was not upset as I was with the girl that asked me why I was wearing a skirt, a couple of hours before...

Also people usualy get really desapointed when I replay to the question with a "yes, Im using underwear". But know I think the question very unpolite and now I answer "Do you want to see"?
