When I worked at Toys R Us back in '98 I usually had an 8-5 shift. One day at the end of my shift my manager asked me to stay late as we had an extra truck coming in that day that needed unloading. I finished that up around 9PM and wouldn't you know it, we were scheduled to do inventory overnight, so I stayed and did that too. When we finished up in the morning it was 7:30 and my shift was about to start, so I took a 30 minute break and then went back to work. 32 hours straight through.
Was good overtime though.
