I guess since it's been 35 years, I can tell this story.
I was working for a property management company in a major city, that managed multiple high rise buildings in the city. My job was to sit all night, watching the security/alarm consoles, and TV, (Mostly TV) Not much happened at night, there were no computer monitors, just lights, buzzers, radios, and phones.
(The job payed VERY well, and I could go to school during the day, study at work, etc.)
One of the maintenance guys was a buddy, crazy nam vet, a bit too much into substance abuse.
One night he informed me he had some killer weed,and if I could figure out a way to leave my work area, we'd sneak out to the loading dock area and smoke it
The solution was kind of a meeting of the mindless. I was half-asleep, he was half 'lit'.
Somehow we decided that we'd get a rubber band and pen, and use the rubber band to hold the pen down on the push to talk button on my walkie talkie, leave it near the monitoring console, so we could go to a remote area to smoke, and hear any buzzers or phones ringing in the office.
The problem was, the radios were all on one network. so every other maintenance and security guy on duty for that company at 0300 could hear us.
We had to mess with the radio a bit, make sure it was working, and I'm sure we were discussing what we were up to.
There should have been 15-20 people awake and able to hear us at that time of the day. Not sure who was sleeping, or who was dumbfounded or discrete, but I didn't get fired until a few months later for some other incident.
