Mind you, I had something similar happen to me on the Manchester 100 once! I got a lift to Wythenshawe Park and was getting a bit desperate by the time we arrived. That second cup of strong coffee first thing might not have been a great idea!
So I headed for the toilet block only to find it chained up. (In later years, I noticed that there toilets in one of the other buildings.) In desperation, I jumped on my bike, rode off and found a bush at the far end of the park. I was about to avail myself of its cover when a dog ran up to me followed by its owner!
Back on the bike. I sprinted off to another bush, Our popped another dog and another dog owner!
Things were getting critical. A mad dash took me to a huge bush at the far side of the park. I dived in and, er,
'All became a burning mist' as they used to say at the end of Mills & Boon romances!
Ah, blessed relief! Then a sound began to percolate into my consciousness. It sounded like traffic and people talking. I swivelled round to find my a*se hanging out the back of the bush next to the park railings by a bus stop!
