or worse, will they just laugh, or shake their heads in disappointment?!!!
Hey, you can expect a few jokes, but you shouldn't take any of that as a personal insult really. (I mean, I can laugh when my Polish friends try to speak Dutch!) Besides, most tourists who visit Poland don't speak any Polish.. So even if you might know a little, I'm sure your attempts will be greatly appreciated!
Have fun! (You might try a glass of water!)
