I parked my car under a tree for the last few days and decided to take it round to the car wash at lunchtime. I do tip those guys even though the daily mail has made it quite clear they are all money laundering operations.
I'd be more inclined to tip for a mugging than a Hermes delivery. I'd be more likely to pop down to the opposition dug out and tip the manager after a Saturday afternoon thrashing (yes, Kenneth) than tip a Hermes driver.
