This guy that handles passengers awaiting wheelchair assistance, is extremely rude to passengers and all people waiting for assistance on boarding flights...We were handled like children and told its not fair that a cleaner had to help us wipe up a little juice that messed by our chair. The passanger before us had words due to his unnecessary rudeness. This person must please rather not work with passengers as he does not know how to talk to people. I did complain to our host at the wheelchair department and was told the rude assistant is new. Please follow this up as i amongst other passengers, think its extremely bad service.
