Oh my Gosh, I forgot my favorite ploy for panhandlers asking for money on the street.
I tell them in my limited Polish, that I don't understand what they are saying. Of course, I have not tried this in Poland. There I would use my limited German, but it works evertime in every other place like Montreal, LA, etc.
One Guy cracked up laughing, that I 'really got him good'.
I will have to remember my limited Polish for all flights other then LOT airlines.
