Interstate buses go to, 2 Waterbury's, 3 Hampton's, and 7 Springfield terminals!!! So, which one are you going to?

I remember the story of the Toronto traveler, we'll call him Mike, who got on a bus at the Toronto bus terminal after his cousin, who was a professional hockey player playing for the Portland Pirates in Maine, asked him to come visit him. Mike sat in the back of the bus, and after several bus changes (Mike asked the drivers at each terminal which bus to go to) he moved closer and closer to the front of the bus. Finally, after a couple of days, Mike sat in the front seat and the driver chatted him up a bit.

Where are you going?
Mike answered: Í'm going to Portland to see my cousin play hockey for the Portland Pirates. Mike had never before visited the U.S.

The driver paused for a moment, and asked "The Portland Pirates?"
Yup! said Mike.

Well, I've got some bad news for you...you're about 50 miles from Portland, Oregon! The Pirates play in Maine four days travel from here!

In fact, and this is a true story, Mike was following directions from drivers according to his ticket which was sold and printed to the wrong Portland, on the wrong coast.

Upon arrival on the West coast, Mike called his cousin on the East Coast with the update on his travels in the wrong direction, and got a reissue ticket and returned with four more days on the bus to the Portland on the East Coast. Upon arriving at his cousins hotel, Mike found out that his cousin had just been called-up to the Washington Capitals (the NHL affiliated team) and was no longer in town!!! But, at least his hotel room was paid for! (The hotel front desk threw in a complimentary map of the U.S.A upon checkout!) True story!!!

Ever since I met Mike I have been adding the city, and state in my destination announcements, and I have had numerous instances where a passenger had boarded, but thankfully realized he was on the wrong bus. For instance:
1. A passenger boarded my bus with wrong destination, wrong ticket. (I.e. I'm actually going to Springfield, Virginia).
2. A passenger boarded my bus with wrong destination, right ticket. (I.e. I'm actually going to Worcester, not Boston. I asked for Woston (pronunciation) at the ticket counter.)

Sometimes, it's the ticket agent's error. Sometimes it's general miscommunication between the customer and the ticket agent.
Sometimes it's wrong information from an information clerk at a large terminal i.e. your bus loads from such and such gate and the driver accepts the ticket which may have some errors on it. Whichever error there is, a comprehensive boarding announcement is the final stopgap to a very disappointing misdirected journey.
