I'm not sure if it's the fact all parties are a little more relaxed in that moment or if coffee has magical powers,
Excuse me? Lol you must know of the legendary magic powers of coffee by now! Everything and anything is possible with enough coffee. "Give me a leverl cup of coffee - and I can move the world"
As I just quoted in another comment...A wise quote I devised in about one second:
Good coffee is god, bad coffee is bad.
The end.
