Fucking angels, Dean thought. Everything had been fine until Cas went and got himself a Slushie.
Dean had nearly choked when one of the angels asked Cas why he had "red like Hell". Cas corrected him, telling him it was only cherry. Suddenly, they weren't having an Angel Meeting anymore. They were having a lesson in humanity.
Cas tried to tell them he was allowed because he worked there. That it would be stealing if anyone else took one. Humans lived off money. Without it, they struggled to survive. A dozen slushies wouldn't go unnoticed in the store inventory.
Swamped with disappointed angels completely fascinated by the machine, Cas' eyes had met theirs in desperation, and Sam reluctantly took out his wallet and put a twenty on the counter next to the register.
"Child size only!" Dean ordered, as cries of "I want blue like the sky!" and Cas' "That's blueberry" filled the room. Dean watched as his friend helped everyone fill their cups, then leaned over to his brother. "We are never holding a meeting in a Gas'n'Sip again."
