Twining

A con wherein the con artist gets a cashier to give the twiner more money than s/he gave the cashier plus their shopping for free. Here is an example of how the con might go: 1. Twiner buys a 60p packet of chewing gum with a £20 note. 2. After receiving £19.40 change, twiner 'remembers' he has a £1 coin in his pocket. 3. Twiner gives cashier 5 X £1 coins and asks for a £5 note in return. 4. Twiner distracts cashier with small talk and slips £5 into his pocket. 5. After the cashier has been engaged in enough small talk to make them forget about step #3, twiner gives the cashier a £5 and a £10 note and says, "Actually, you might as well just give me the £20 back." 6. If the twiner is good and the cashier forgetful, the cashier will give the twiner a £20. 7. Twiner now has £25 and a pack of gum from £20.
