I don't have any problem the way you might say "croissant" in english. I'm, however, in a feud with all those ignorants that like to point out how french prononciation is ridiculous using croissant as an example. "You should pronounce it k'r'o'ee'sssssssss'a'n't nianiani niania nia" !
Croissant is actually a great example about prononciation of a french word. Not exception or weird non written rule involved.
