Since the Etihad/Air Serbia flight from Abu Dhabi was late contrary to assurances we arrived in Belgrade ten minutes before our connection flight was to take off. The security staff at the x-ray checkpoint took their time though while the Air Serbia personnel at the flight gate in plain view were calling us to hurry as if the delays were our fault. They started by checking our duty free allowance and receipts then the hand luggage to check our watches and jewellery (we were moving back to Europe with all our belongings) and then had to wait another few minutes to have my shoes x-rayed. When we finally departed the clerk was still working our still screens. We flew from Sydney for 24 hours then. We have been re-checked in Abu Dhabi. We have just descended from the previous flight and we have been escorted to the checkpoint. What was there to check so thoroughly again? Since when were watches and jewellery a security point concern? Or was there an over zealous clerk on duty? Aren't there any clear instructions of what they are to check? If not we may be subjected at the discretion of a clerk to unnecessary and diminishing check-ups. In any case we decided not to use this route again.
