The bathroom is flooded again...

The bathroom has flooded yet again. For those not "in the know", the normal height urinal systematically floods the bathroom when flushed. This leaves me with the choice of using the "midget urinal" and peeing on my shoe, or using one of the germ infested stalls. Today facilities thought they would be cute and put a "Happy Birthday" sign complete with baloons which reads "Out of order" on the urinal. In a few hours, the plumber will arrive, fiddle with the urinal for 5 minutes and declare it fixed. Next week, the process will repeat. This has been going on for over a year.
