If I encounter that, I have no doubt how I will respond.
I am going to line up my shoulder squarely with his shouder. And I guarantee my path is not going to deviate an inch. After the collision, I will turn around, and in a voice with a gesture like John Belushi gave after he smashed the guy’s guitar in the movie “Animal House”, I will shrug my shoulders and say: “Sorry.”
I used to be a hockey player so I know how to do that.
I've seen a young Middle Eastern guy arrogantly cut in line at a grocery store to stand in front of an old American lady. (He didn't get away with it). I have noticed that when I dash into the corner store for my one vice, a pack of smokes that lasts me for at least three days, I notice that if I'm wearing a sleeveless shirt and/or it is too short to cover my rump in my jeans, they are cold and distant, sullen. On days I'm wearing long sleeves and a loose tunic-length top, they are civil and amiable.
Creeps. I buy my smokes somewhere else now, by the way. This thread is great -- now, when I do business with Middle Eastern folks in my own work as a kind of contractor, whether or not they greet me first will tell me quite a lot.
