I built our slack bot messages so that they are prefixed in BIG LETTERS with whatever system they originate from, i.e.:

"DEVELOP: You are a useless product manager"
"STAGING: You are a useless product manager"
"PRODUCTION: You are a useless product manager"

One of these is when a payment is made on our platform. Our lovely product manager proceeds to message me, "did you just trigger a payment in the test system?".

YES, OBVIOUSLY I DID SEEING AS THE MESSAGE HAS THE GIANT WORD "STAGING" IN FRONT OF IT!!!
