Back in September when I was shopping for a suit for a school formal dance, I happened to get very lucky due to a screw-up.

Since I was only going to be wearing it once I went to the cashier carrying a £40 suit that was price seperatly for the jacket, trousers and tie. The cashier was obviously new and when she saw the price she exclaimed "Wow! That's really good value for a suit!", charged me and then turned away. I walked out of the shop with £33 in my pocket, she had only charged me for the tie.

To be honest, the shop probably deserved to make a loss on a product, one of the more expensive jackets in the shop had a price-tag of £299.99. So I sincerely doubt they were upset when the cashier tried to buy the same suit and claimed it only cost £7.
