The last time I flew into Blackpool, the payment of the GA Landing fee was 'farcical' to say the least....
After hunting around the reception and 5 offices in the terminal, I was told that they had no facilities for taking a cash transaction, and they would send an invoice (with the payment for cash discount) to me in the post.
This arrived, not to my address but to the flying club's address, and I don't think it had the 'cash discount' added (it was about £20 from memory.)
So please next time be aware that GA Pilots like to walk to the building with the Big Yellow C, and then meet a person sitting in front of a wooden cash register, where they can instantly hand over their fees. (cash or plastic.).
We also don't appreciate being bombarded with X-Rays or having to wear yellow jackets....
