We have a sandwich shop that runs 24 hrs from Tuesday morning until Saturday night. I’ve picked up late night supper there and seen people playing cards, etc and just generally hanging out for long stretches.
When I was younger my buddies and I went to a 24 hr diner and played magic into the wee hrs, occasionally leaving only when the earliest breakfast crowd started to roll in.
Our office I’m actually going to give them props for this - they do these events during work hours. Summer bbq? Close office 4 hrs early and it’s free drinks and food for everyone. Annual golf event? Tuesday at noon, you can work or you can golf, your call.
Granted I’m too busy to partake for the most part but I’m not a clock puncher, and if I was, I’d appreciate the effort.
