I wonder why, Muslims only make up 5% of Germany's population, fiscally this wouldn't make much sense given that they would have to make a second exam paper & provide more labour

For some people, not everything is reduced to being as cost effective as possible.

Come to think of it, it was quite nice how they accommodated Muslims; however, they could have just postponed the exams.

the German's regain some reputation for hospitality.

Terrible idea and precedent IMHO.

Why?
