There was one man who used to walk around and pretend he was driving a truck. Making the noises and steering, reversing whilst beeping etc. He used to get served at the drive-through at mcdonalds.
I've heard many a story about this guy - including one from a mate's dad that involved him getting a group of shoppers to help him reverse park his particularly unwieldy imaginary articulated lorry into an ASDA loading bay.
I actually played a basketball game at Bridgwater college sports hall the other day - i don't think it will have changed much since you've were last there.
