In Brum the taxis came up with the idea of dropping pax outside the IBIS Hotel entrance (it's close to the terminal). That worked for a while until the Airport Gestapo got wind of this and began to fine them 60 quid a go!! If you know the BHX airport layout you will also know that a quick drop off at the IBIS is pretty harmless and does not block traffic flow. The airport authorities just needed to protect their fat cash cow. It's really disgraceful.
