Maybe it's just because I don't drive and regularly use public transit in my own city, but I find Disney's bus drivers to be very magical.
They smile when you get on the bus! (Sometimes you might need to smile at them first, but that's hardly difficult.)
They'll tell you interesting stories if you're standing at the front of the bus. Try asking them where they come from some time!
On several occasions during our visit last week, drivers DID tell jokes and play trivia games. They sang happy birthday and happy anniversary and welcomed "princesses" on board. And even when they were quiet or didn't speak English well, they were unfailingly polite and professional.
The guests were always more of a problem than the drivers. I was a bit ticked at a family in the back of the bus, one trip, who were mocking the driver during a trivia game. My husband and I ended up calling them the "Goobers" thanks to their inability to grasp that Steve Gutenberg is an actor, it was the answer to one question, and we're all moving on now. "What'd he say?? GOOBERberg! Ha, he said GOOBER. Hyuk, hyuk! That's not a name!"
They were very special people.
