The taxi driver must not have been too happy to get a request to go to the Sheraton. They wait a long time to get a ride and want higher fare trips. However they cannot turn you down.

A few years ago my AA flight to London was delayed 10 hours. They gave me a free voucher day-room at the Ramada. I waited over 1 hour for the shuttle and called twice to ask where the shuttle bus was.

Finally I was so frustrated, I gave - up.
