Consider this scenario…
You land at a Security Controlled Airport.
You shut down and are about to head into Town, when a person strolls over and demands to see your ASIC.
You say, Sir (or Madam) I demand to see the paperwork giving you the authority to see my ASIC!
After the stunned look disappears from the apparent Officials face you say….
SIR, you are upsetting and harrassing an Aircraft Captain, and I demand to exit the Airport without further interrogation.
Silly scenario I know, however we shouldnt have to go through this possibility when landing at an Airport and simply wanting to go into Town and support the local economy!
