One thing that always struck me as odd is how the culture is seemingly the opposite of this in apparent beer meccas like Belgium - not only are the glasses typically much smaller (this is fine) but they also leave massive gaps at the top. The glass capacity is never treated as being close to the rim at all.
He explained after pouring it better that, even the remaining head (It had ~3/4 inch even after fixing it) might still be met by derision by many customers. "They'd be asking if you would be charging them for just for the half" etc.
There's a bit of leeway but you'll quickly hear about it if you short a pint too much.
McDonalds cups have a line for ice.
This would have been in the late 80s - i've no idea if it was still in use, but i've a feeling that the law hadn't necessarily moved on, so I guess the official measure could have been required if challenged in court.
Also a great way to teach folks on how to hold others honest and accountable, a skill sorely underdeveloped at present. Start with the pours, and push upward from there.
I volunteer for the pub equivalent of this.
"A mega pint?"
Germans have it nailed down with the Kölsch Stange, a 200ml glass that so readily disappears that it stays cold and you just get another from the Kranz.
That is quite surprising. What breweries used to do when I worked in cafes and bars was to paint a mark on the glass and under it write "0.5" (in market that sells in liters and not in pints) and this mark is above[1] the half liter mark. Note that it is without units.
Pubs and bars get glasses for cheap or free and the brewery/distributor tries to trick the bar into selling more beer than they expect.
[1] We checked using measure cups from the kitchen. Maybe there is a conspiracy to have kitchens use too little ingredients.
If we mandate beer volume then places that are “shorting” you will just raise the prices. Not to mention the tax on beer that would be required to pay for the inspection service. No one likes feeling like they got less than they paid for, but there’s solution is to take your business elsewhere.
Also, you know what really annoys me? When a bartender pulls a pint for me, and it’s up to the brim with no foam. Foam is part of the joy of a crisp beer. It adds aroma and anticipation. If I wanted to drink something with no foam I’d drink a soda. And in my heart of hearts (or stomach if stomachs?) I fear that’s where these arguments lead.
The "loss of the pint" is basically shrink-flation. When a bar's costs and/or overhead goes up, they must do some combination of cutting expenses and raising prices. Raising prices means either selling the same stuff in the same quantity for more, or selling cheaper stuff OR less of the same stuff at the same price. Most bars will opt for the latter options to avoid raising prices, because raising prices is more likely to create complaints. All caveats apply, of course -- drop portions or quality too much or too often and you'll get complaints for sure, but "within reason" it's the lesser of two evils.
This is why I personally don't feel like I'm being cheated out of 2oz when I buy a $8 14oz shaker pint of IPA. Clearly, the cost per oz at this bar is $0.57. A 16oz glass would cost $9.14. They don't owe me the 2oz for free just because they used the word "pint". If the state government started enforcing pint measures again, bars would just drop the word "pint" from their signs and menus.
Rationally, you're paying way more than the liquid in the glass, so just mentally tell yourself that the haircut is included in the price, and that's fine. If you can't stand the price anyway, change bar.
You're there to chill. Just chill.
Bickering over a few dollars when you're paying a premium price for the experience of going out is rather silly. There's better uses of your time, like enjoying yourself.
