a pal works in a Mercedes parts shop N W london, and has bragged about how he sold a part incorrectly to a customer with an extra "0" at the end of the first figures, cant think what, but you know, if part was £5, it was £50, if part was £50 it was £500 etc.
Im sure it was the latter as he mentioned he made a hefty mark up, and the parts manager paid for him to have dinner at a restaurant (literally).
