I doubt that really happened....... it sounds like a variation of other Urban Legends that have been floating around with the same theme:

Make no mistake, as a veteran I would be livid if something like this happened, but we have to be careful about what we circulate. If this is indeed false, as I suspect it is, then by passing this information on we could be harming an innocent business while fueling hate towards all "Arab looking" men.
We really need to make an attempt to verify things like this before we forward them on or post them in a public forum. Just my 2 cents....
