No, but whenever you have something that's countable (even if it's just 1), you have to do <number> <measure word> <thing>, so instead of "I have a ticket" or "we want 2 waters", you have to do "I have 1 <measure word for flat things> ticket" or "I(plural) want 2 <measure word for cups> water".
There's a generic measure word, but I think it's seen as improper to use it.
