Sandia shuttle did not inform me where I was supposed to wait for my return shuttle in the Albuquerque airport (en route to Santa Fe). I waited outside where the shuttle buses come arrive outside, near luggage claim. A few minutes before the bus was scheduled to arrive, I asked another shuttle driver where Sandia shuttle left from. He informed me I needed to check in at the Sandia Shuttle desk ( I haven't flown in years and was not familiar as to where that was). Once I approached the shuttle driver and told her I needed to take the next shuttle ( I just missed my shuttle) she rudely stated to "wait over there near the ladies room by those chairs). She was very unprofessional and clearly demonstated she was unhappy in her job. The woman in line ahead of me, had also missed the shuttle, and the shuttle clerk was very rude to her also. We paid $45 round trip for the only airport shuttle service between ALbuquerque and Santa Fe, and they have the nerve to treat their customers with disrespect. On the shuttle, some of the other passengers were also complaining about the rudeness of the "clerk."
