Don't forget the complimentary chocolate too!
Ah yes,
I forgot about the Swiss chocolate ... And also that one could buy (non EU) duty frees on the ZRH route.
One flight I'd forgotten to bring my "Miles & More" card for my duty free purchases, with a smile the C/A presented me with her pen as a reminder not to forget my card next time ... Later during the flight I asked of her if I could swap her pen for another beer, she just smiled telling me to keep the pen as she presented me with another beer.
Another flight, obviously a new C/A came round with the duty frees, I asked for "400 Marlboro Gold please", she gave me a confused look asking "Are those cigarettes?", I smiled and replied "You don't smoke do you?" ... she just cracked up laughing
