It’s also a few days into Ramadan, a holiday where Muslims fast while the sun is up. (It lasts approximately from fat Tuesday to Easter.)
So, you know, if you want to fuck up someone’s day, make ‘em work extra hard while hangry.

(Which is not necessarily true. IIRC, much of the religious understanding and forgiveness in Islam is about intent. They might be cool with breaking a fast when facing an existential threat. But it’s Iran, sooo…)
