The thing that all the successful supermarkets (and other truly successful businesses) learned years ago is that you make it easy for the customer to buy, and whatever it is you sell them, they feel that it is fair and good value.
The pax aviation industry seems to have lost sight of these simple business tenets. In this case, the industry is "selling" a journey from Leeds to somewhere else, and not a series of individual components that are mutually exclusive, Scratting around for change at each stage of this journey makes for inconvenience and a feeling of being conned.
And please try and explain what on earth is the economic logic for not charging for an hour's parking and provision of a bus journey from the car park, but charging for a drop off where the customer transports themselves ?
Finally, the benefit of half an hour for your 2 quid is no benefit whatsoever for the colleague who drops off a business-associate without any luggage in 10 secs, but then has to spend extra time finding cash, queueing at the barrier etc., and subsequently writing up an expenses claim.
