When I was in school, this sort of happened to me at a school clinic waiting room.
I was crossing my legs in the American style. Without realizing my feet were pointed at what appeared to be two middle eastern men and I noticed they were giggling. I noticed and put both feet down and immediately apologized to them. They were impressed that I knew and it made for a good ice breaker (however culturally risky).
By pointing, do you mean the soles of your shoes were facing them, or were the feet pointed in the direction of the men in the normal use of the word pointing? If it was the normal use of pointing, how do you avoid having your feet pointing towards whomever is in front of you when you walk? I'm really just trying to get a picture of the situation here.
