I love this concept and would love to see it in place in the US. Too many places are stocking these pint looking glasses that are actually 12 oz.

Kinda on a similary vein, just last week we went to an irish pub that recently opened and was super busy. They pride themselves on 20 oz. imperial pints but since they were so busy...they resorted to 16 oz. Solo plastic cups as they couldn't clean glasses fast enough. After we paid our check (we had dinner) a manager stopped by and cleared some plates and I pointed out they shouldn't be charging full price for the plastic cups. He asked what I meant and I showed how their draught lists gives the beer prices at 20 oz. but the plastic cup is only 16. He offered to give me another one and I told him "that's not what I'm looking for." He said, "no, you're right. Let me get you another one." Just think how many people got overcharged 25% by accepting the plastic cups.
