An old office of mine allowed me to view our lobby, a lunch area and outside smoking area.
Some fuckers literally got there about 1 min before getting dinged for 9:15 instead of 9:00am, went and made coffee/talked for 30 mins. Went outside and smoked...came back in and did coffee...went to the restroom...made another coffee and went out and smoked again.
Sometime around 10:30-11am they went upstairs, which is about the time I take my lunch usually. a little prior to noon they were back down and out to lunch until just past 1am and clocking in. More coffee, go out for another cigaratte, usually a LONG restroom break with a book and get another cup and head upstairs sometime close to 1:30-2pm. Then about every hour downstairs for a 15min cigarette social break until one last final one where they just watched the clock until 4:52pm to clock out at 5.
They probably ended up working 3 hours in any given day.
When I was younger there was an old guy that would bring the paper in after lunch and camp out in the bathroom until he pretty much read the whole thing we all guessed. The problem was we had one restroom. It was literally locked with him inside it from about 1 to 2pm everyday.
