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.
