I do think the wheelchair use at airports is abused - which is a shame for the genuine wheel chair users. When checking in at Malaga a few years back they used our queue for all the wheelchair users and their families, as and when they arrived, it meant that we stood in the queue for almost an hour and only just got our flight, our seat numbers had already been called out when we got there. To make matters worse, one lady who was in a wheelchair, was in our disco every night dancing away !
Likewise, it is amazing that going out to Malaga last March, about 8 wheel chair users were taken on the plane first - quite understandably - but when we landed the stewardess asked all those people needing assistance to stay in their seats whilst the other passengers disembarked - by the time we got off there were only two left - the others had suddenly decided that they could walk and got off first !
It is not surprising therefore that some wheelchair users get a bit of a cynical look - it is a shame for the genuine people who do need and appreciate this assistance.
