When I was a fairly senior FO, flew YYR to DTW, turn was shortened due to MX, so just sucked it up and then flew to SLC. Still had to go to MSP, so I asked the Captain ( Long sleeve guy if you know what I am saying) if he wanted anything to eat as we were deplaning in SLC.

"You are gonna cut it pretty close aren't you?"

"I wasn't asking permission"

Fairly quiet flight home (left on time BTW). Told myself I would never be that guy.
