I worked in a Retail Place that had a problem like this, but it was pre-cell phone. I was on a crew of three stocking shelves; we were pretty autonomous. One guy on the shift would clock in at 6am, then grab a newspaper and camp out in the bathroom for half an hour or 45 min while the other two of us worked.
Other guy and I complained a bunch to managment. Finally, the manager held the guy's time card, made him pick it up in order to punch in and out. Just the fact that someone was paying attention (much like the company in this story) cleared the problem up, pretty quickly.

They punch in, go to the shiiiter and sit there. When asked why they didn’t go at home before punching in, they said “I don’t want to use MY water!”
