There was no security concern from a safety point because the money was all from the previous day's onboard sales, counted up in the crew room, which are all airside in RYR, and recorded before being bagged up, so the bags and their contents never crosses the airside/ground side cordons. It was standard procedure to have one of these bags every day from every base on a designated DUB or STN flt. The bag was stored in a reasonably secure manner. My only concern is that I never saw the pursers get a receipt from the office staff who came tot he aircraft to collect it, but perhaps that merely occurred out of my sight. I never saw a NOTOC, and I honestly don't remember an OM-A reference, but there may have been one. But it was certainly a long standing daily procedure for every base (except STN and DUB, obviously).
