A few years back I was in a Construction site trailer at 1200 and the ‘Johnny on the Spot’ guy showed up.
The ‘house’ was near the trailer and the guy started pumping.
When asked why he showed up at 1200 while lunch was going on he explained that the ONLY time he knew the facility was not in use was during lunch or break time.
NOBODY ever used it on their own time.....
One of the tactics I learned from older female coworkers who pretend we’re all working union jobs (we’re in an office environment with no union labor) is to use the bathroom BEFORE it is time to go home - so I don’t waste my own time after my work day...
