Did they applaud when the plane touched down?
I've landed in an assortment of countries and very seldomly do I hear clapping on polish flights. in my experience clapping on planes occurs in less developed countries. Especially those for whom disasters are a regular feature in their country.
And although we might poo poo clapping, if you are a native of a disaster prone nation then really clapping is not such a silly thing to do.
some bit#h tried to take advantage of me yesterday...
Ha. yup had a similar experience with a shop keeper who claimed i gave her 10zl not 50zl and administered the change for a packet of cigs accordingly.
i preceeded in my rudimentary polish to go of my head. This worked very well and she promptly gave me the correct change.
When people try this on I advise becoming extremely angry and hopping from one foot to another screaming obsenities.
