I know we all complain about the strippers/guys on the floor not going for the amateurs but i wonder how hard it actually is for them due to the obvious language barrier.
PH is filmed the Czech republic. The black stripper is British, the bald headed guy with the hairy chest and beard is German, all the stage strippers are Spanish etc. It must be hard for them all the communicate with one other.
It's an interesting question, especially in a crowded and loud environment. That said, it's much easier to speak a language well enough to do a job than it is to speak it in general. You need to know around 20-30,000 words to have a conversation, but only 1,000 or so to discuss a particular topic. I imagine most of the strippers speak Czech well enough to get from soft sounding white lies like "the check is in the mail" to "the male is in the Czech".
