While at Uni I worked in the Co-Op at the end of our road and hated the job, but needed the money, however on my last day (just before my final exams) an idiot I worked with kept going on about covering me with flour, I made it pretty clear that I wasn’t in a very playful mood and that it would be a silly idea. Later in the evening I was walking towards the office when he decided to try and ambush me, I knocked him out and the bag of flour he was holding landed on his head! I did feel a little bad, but finished the shift and passed my exams with no further repercussions.
