Come to the thread late, so apologies.
I back up Flying Torqwrench's insistance that Spanish Aircrew get preference.
We were in Alicante some years ago and received an hour delay when we called for clearance. The first officer, from a Spanish speaking nation, got on the horn to ask the reason why (in Spanish of course) and we got an immediate clearance to push and start.
He therefore, is correct. It may not happen always but it does happen.
