Extended Play
In order to extend a playtime, the entire school would throw their bags into a massive teetering pile toward the end of break. Obviously the teachers couldn't allow us back into class without our bags, so they all had to be sorted.
Midland Extended Play
Extended play became even more extended when the Midland (the only local bank) offered every child a free low-rent black nylon holdall, if they opened an account. By the time we'd sorted over a hundred identical black bags to their proper owners, it was dinner time.
Except for the flash cunt with the Head bag, who went in on time and had to do some hard sums.
