What does "Out of Service" mean to you?

We posted an "Out of Service" sign on a stall door in the ladies restroom at work because someone (who shall remain nameless because like every other customer, they didn't fess up that they had broken something) managed to break off the flushing lever. I'm not kidding. We found the lever on the back of the toilet's tank with nastiness in the toilet bowl, of course. I suppose we should have been thankful the customer didn't try to flush the lever, that would have been a real mess.

Once we found out that the lever was broken we closed the stall door, put up the sign and left the broken off piece on the back of the toilet's tank to be fixed when time permitted.

Since that stall was obviously "out of order" we posted this sign on the stall door to ensure no one used that toilet. The sign makes it fairly clear that that toilet is out of order, yes? As in, don't freaking use this, right? Yeah, so apparently not.

You see, a brilliant customer used said toilet even with the huge sign taped on the door. It's not like there were no other options. This is not the only toilet stall in our ladies restroom. Said brilliant customer used the toilet and then had the gall to come out to the cashier to hand her the broken lever and state, "I couldn't flush because the lever was broken off."

No shit lady. We know you can't flush it and we know the lever was broken off. Thus there was a sign CLEARLY posted NOT TO USE THAT STALL.

What we learned from this is that "Out of Service" means different things to different people, apparently. Well, that and we absolutely have the most idiotic customers in the world. I try to never underestimate the stupidity of others but I gotta tell ya, at my job that's hard to do at times such as this.
