I worked in a warehouse a while back and some old git would time us when we went the toilet, one of the lads always took ages just to piss him off and ended up getting pulled up by the boss about it. Needless to say this did not go down well so we hatched a plan to get revenge, he brought a pair of spare boots into work and placed them in the cubicle, we knew the old git had seen him go in so we knew he would timing him, 10 minutes later he was fuming and went to get the boss so they both go into the toilet while we where all pissing ourselves laughing, the look on his face when he realised the cubicle was empty was a picture. The jobsworth twat.
