In my clubbing days I found that people would regularly steal my pint of larger when I hit the dance floor. I decided that enough is enough and from then on regularly took an empty plastic pint glass to the toilets and filled it with my urine. I'll strategically place the amber nectar in an inviting place and wait to watch the *******
drink my piss. It's a bit like arsonists who hang around to watch the fire crew put out the flames.
