we don't sell high gravity beers (over 8%) in full pints - halves only.
This I have no problem with. But it should be disclosed when you order. I'm often a little frosty when I order a beer, it's pricey, and it comes in a tiny snifter.
If you tell me upfront, that's OK. Some places list in on the menu, others do not. I've had the server tell me, too, but sometimes it's a total surprise. Well, not really a surprise as I've come to expect it. But it should be disclosed.
