Not very good for business!
Actually, that's a bit of a sore point.
The whole of Fes has run out of Jiffy bags and I need some to post things to people.
It costs much more to post boxes.
I went to one shop and asked and the man said, "Ah, you speak Arabic?"
"A little" I replied modestly.
"Are you a Muslim?" he asked.
"No" says I.
"Then i shall not speak to you" says he!
The first time this has happened in 13 years!
If that happened in the UK, the other way around, there would be uproar and accusations of racism!
