When I worked at a shoe store there used to be these men come in there that dressed just like Osama bin Laden. Long scraggly beards, long white robes, sandals, diaper-like turbans, etc. And yes, they stunk really badly, like they'd bathed in camel dung.
I could have gotten past that if they had just acted human, but they gave everyone who worked there a hard time. They haggled over the shoe prices and when we wouldn't budge, they would buy them and then return them a few days later smelling like camel dung.
Then they would come in every week at least and do the same thing. Sometimes they would get the shoes all mixed up in different boxes. One time they had a little boy with them that was making gun motions and sounds at one of my co-workers.
I would have LOVED to tell them to get their jihad up on out of there and that we don't serve people with diapers on their heads and we didn't like their kind.
