Would you call this discrimination?

I walked into a shop in Melbourne's western suburbs today.

I saw a sign on the wall that read:

"Female staff required for Ramadan - Arabic speakers preferred"

Is that discrimination?

Compare it with a supermarket advertising for "Female English-speaking staff required for Easter".

And the stupid thing is that if they were bright enough to write the sign in Arabic, then the rest of us would not even know about it.
