Just because you report it doesn't mean you did it. I think you can usually tell the front desk that there is a clogged toilet in the ladies room and they will call maintenence. I have never clogged a public toilet but I have clogged the toilet at my friends house, that was quite interesting.
It's harder to report it when you're guilty. THe other day I was at a restuarant and the toilet was clogged, I didn't do it and I reported it without a problem. I bet if I were the culprit I would have thought twice before reporting. They probably thought I did it...
Anyone else ever embarrassed about buying a plunger? I feel like buying it is like saying, "I clogged my toilet and I was too lazy to prepare properly for this so I had to rush out at midnight for a plunger". I never buy one until I experience a clog. Needless to say I move a lot and always assume i'll have the incredible uncloggable toilet.
I think about useless things too much.
