I ate something in a B&B in Coventry once. That night I had to go, sharpish. It wasn't very nice and pebbledashed the toilet which despite my efforts, was obvious to my room mates. I decided that it was time to hesad home.
There are 5 service stations between Coventry and my house on the M6. I've been to each and everyone of them for a poo now. Driving very fast inbetween. if a copper would have tried to stop between stations, I'd have just carried on, maybe waving a childish drawing of a poo out of the window to attempt to explain why I was still doing 110mph.
Once I eventually got home I stayed in bed for three days. Bed-toilet-bed-toilet. Vert unpleasant food poisoning.
