It was a long time ago, so I don't know if this has changed. It wasn't just the waitrets that were scanty, it was the pints too.
I know it was Arizona, I know it was hot, but even by my standards the first "pint" went down awfully fast. So did the second, so for the third roun d, I ordered a can of something. Poured it into the pint glass and the 12oz can filled the "pint" glass to the brim
I wrote to the AZ equivalent of the TABC - never heard back, never heard from the TC. I hope the new one in Grapevine, TX doesn't mislead by calling a 12oz pour a pint. Of course they won't - everything is bigger in Texas.
Of course these woossy 16oz pints are shameful too. A many pint is an Imperial Pint at 20 oz!
