these limo drivers are actually not employees of the hotel. they are only contracted by the hotel to serve their clients.
had a terrible experience too. i got a limo service from Four Seasons Hotel to my flat in Al Ghanim. i showed him the fastest, shortest way. when we reached the front of our building he asked me how i know that way. i said "of course i live here". then he said he doesnt know how to go back. WTF!!!
