I bet YOU thought they were....

When I came to pay for the rear ring bearing repair to my BMW, I was sent away from the dirty workshop to a carpeted section of the building with smart desk and a winsome young lady with a credit card machine.
This is the itemised bill: labour: 21 work units at 220 euro. new bearing: 77 euro. Oil seal for the same: 25 euro. The rest are sundries, oil and VAT at 20%.
After I'd paid, the young lady, with a smile, slipped me the two little green packages. That doesn't normally happen when I pay a bill. I haven't opened them yet, but I guess they are mints.

....wet wipes.
