Not sure if this belongs here or in the "What's the deal?" thread, though maybe it belongs in a little bit of both threads. But in Cheech and Chong's Nice Dreams, Chong ends up trading their money in for a bank check, which I think was for the same amount they had (I haven't actually seen the movie in a long time). Cheech tells Chong that the first rule in drug dealing is "never accept a check". I don't know why not accepting a check would be the first rule, but then Cheech gives some points which seem irrelevent to being a drug dealer... He mainly points out that they don't have any identification to use when they cash the check (and that Chong doesn't even have a library card because he can't read)... So... Anybody know what the big deal is (though I'd like to think that there aren;t any drug dealers on this site)? Could it just be a case of bad writing?
