Out of the Mouths of Babes?

Last weekend the three of us were out, and about to sit down in a cafe for a much needed coffee when we realised that none of us had any money in our wallets. We were wandering in search of a cash machine when Sanjay said "hang on, there's a TAB" and started to pull a slip of paper out of his pocket and walk off with Asher. At this point I was wondering what on earth was going on but it turns out he had been at the pub the day before (with work!) and there had been some question about which horse had one a race and Sanjay still had the betting slip with him. I stood around and grumpily waited for them to get back, assuming that I'd still have to find an ATM but they came back and Sanjay had a strange expression on his face. He'd got lucky and yesterdays ticket paid enough for us to have coffee and cake but Asher, on seeing Sanjay hand over a slip of paper and receive money in return had asked "Daddy, is this a bank?"
