Guess I am curious because I live near a airport and see 5-20 people waiting for a trip. Is there any difference in price? If not why would you sit a hour as it is not a very busy airport? Maybe if you are retired and meet some friends then I completely understand. I see guys at the coffee shop every am so at least when they are done they get enough for a coffe and something to get them out of the house though again was only curious if there was a airport surcharge.
In the taxicab racket, people liked airport trips because the customers were usually going some place. A "short" ride from the port was still $15 in Pittsburgh, often taking people to a classy hotel, people that like to tip. Get a trip to Monroeville (east of Pittsburgh would be $50 ,25 years ago, to downtown like $28.
