We did a single aircraft visit to Practica del Mare with our Puma. On the way back cruising at 1,000 ft just off the Italian Riviera we opened the box to find lots of goodies, fruit and a bottle of Chianti.
When in Rome, so my co-pilot and I had a plastice cup each with out crewman demolishing the rest. It was neccessary because we had our full entitlement of duty free on board.
No effect on us at all. It was the fastest trip from Rome to Cognac, ever.
