Quote From: mrsbuckWhile eating at a local restaurant, my husband and I were within viewing area of pay station. 
A man came up and paid his, bill and while waiting on a friend to pay his bill, he turned right around facing us, adjusted himself on the outside of his pants. When that didn't prove sufficient, he proceeded to put his hand inside his jeans and adjust himself. I have never liked seeing a man do this anyway, but this was pretty gross. 
If you find that gross, you should have been with me to the middle east and India where men were masturbating openly on the streets just looking at a woman passing by. Now that explains why a burka (the black bedsheets they want to wear) is so loved in muslim nations and why covering the body is so much in demand.
