I actually have a simiilar story. I worked at McDs for 2 years, from September '99 - September '01 and one time the bathroom pipe-ing got all backed up. Well, suddenly tellow liquid started to fill the ice containers behind the counters (before we had self-serve drinks) and an employee asked "Who put lemonade in the ice containers?". A few whiffs and we were positive it was urine. After the plumber came he confrimed it. At least a few people got drinks with that ice too.
