Mr. Dietmar Duller is a great teacher; he successfully trained six flight attendants from different backgrounds and nationalities. On the first day he thought us how to make the perfect table setting, letting us practice several times, and showing us our mistakes and the solution. Practicing is the best way to learn! We spent10 hours of training and forgot that we were tired; it was so useful and interesting! On the second day we learnt basic good manners, general guidelines for protocol, cultural differences, verbal forms of address and so many more other things related to business aviation. I was so happy to learn more and more that it was a pity when the course was over. Now, feeling more confident and trying to put into practice what I have learnt, I am proud to have met such a wonderful teacher.
