What's the difference between "biru hitotsu kudasai," "biru ippon kudasai," and "biru ippai kudasai?"


I'm a bit confused. The first sentence I learned was _biru kudasai_ (ビールください).

But then I watched this video:

And I found out there are so many variations. So I wonder what's the
difference? And which one is the most colloquial one?




They all mean the same thing ("One beer, please") but the difference is the
[counters](https://www.fluentu.com/blog/japanese/japanese-counters/).

ひとつ is a general counter for things and is safe for most nouns if you don't
know the specific counter.

いっぽん is a counter for _long_ things like pencils. In the case with a beer, it
means "one bottle" (it says it in the video description).

いっぱい is the counter for beverages. This is the most specific and probably the
most appropriate for the situation of ordering a "drink", whatever a "drink"
is considered.
