For a bit extra the taxi drivers could be persuaded to take one extra in the boot.
Also recall stowing away on 216s' coach returning from the kebab house. On realising it was going way over the other side of the base from us I ran to the front with my hand clamped over my mouth as one of their lasses shouted "He's going to be sick!" and was turfed off just in front of my room. (poetic licence there, I think it took a half hour wander through the bondu to get back!)
I was all of seventeen at the time.
