Sorry, maybe I didn't word myself very well.
If you had to pay a £1 deposit for a trolley at the airport, it would be unfortunate but understandable. However, BHX charge you £1 for using a trolley, end of story. What if Sainsbury's did that? There would be an uproar.
Surely providing free baggage trolleys comes with the territory of running an airport? Didn't they realise this?
The hefty parking charges should cover the courtesy buses, and the not insignificant airport tax should allow you free use of a baggage trolley, surely?
Standards are only going one way, and it's not upwards.
