Yesterday, close to 4pm, one of the supervisors at work asked me and a few of others on the same shift as I am if we wouldn't mind staying an extra hour, until 5pm, to help build some extra shelving units, since the next shift was a little short of folks to do it. I volunteered, as did three others. After clocking out at 5pm, I came back into the store, because I had to get my grocery shopping done. So, technically, I was at Wal-Mart from 7am-6pm, what with the shopping. I was ragged by the time I got home. Not quite so tired right now though, just wish I had gotten more sleep. I keep waking up a hour to an hour and a half before my clock is set to go off, and can't get back to sleep.
