I agree, and that's why I don't tip the unpleasant ones - so maybe they won't come to work the next day.

To those that say "I always tip because they save my life every day" - do you still tip when the driver...

• is 20 minutes late and you know it's only 5 minutes from hotel to airport
• drops you off in the "rain lane" instead of under the overhang/awning
• drives like a mad fool
• offers no information when you ask "what's around the hotel?"
• tells offensive jokes or stories, or swears at other drivers
• yanks your bag away from you
• drives around the airport two more times looking for more people to pick up

These are some of the behaviors I would not want to reward.

Just wondering if other folks know they're lowering the bar on the van-driving profession by tipping the bad ones the same as the good ones.
