i do...was a school cup game - red v blue - gave a penalty to red (trip in the box - reds were 5-1 up with 15 minutes to go aswell, silly foul) gave a yellow for the foul...recieved a mouthful from the blue player (shocking how much kids know!) warned him about his language, then warned his captain as well who promptly told his player to 'shut it and move on' - that was followed by 'you're a f***ing blind c**t anyway' - swiftly pulled out the yellow again, nice and calm, and produced the red...
that was my first, and thus far...last (ive had a hiatus since and only done few matches here and there)
got a nice little threaten after the match whilst going to my car as well, his dad said 'i know your car now mate, your effing dead!' - unfortunatly for him, i change my car on a regular basis
