"Campaigners are calling for lines to be printed on glasses to show drinkers how many units of alcohol they are really consuming —and potentially to shock them into cutting down to ensure they're getting all the booze they paid for."

That would be a campaign I could support. Actually, some Canadian jurisdictions have long required lines on beer glasses, to ensure that the the customer gets all the beer he pays for (rather than just foam).

It’s a serious matter that: serving short measures, even by having too much of a head on the beer in a pint, can result in law suits in the UK.

Everywhere in the EU has lines on glasses. They DO need that here. I have a calibrated hand and KNOW when I’m being short changed on a pint. There is a cheap sneaky bastard who owns a pub here that phased out all the true pint 16 ounce glasses with 14 ounce glasses. When confronted, by me, he assured me they were still 16 ounces. WRONG, caught short handed. They were 14 ounce glasses but shaped to give the appearance they were still 16 ounce glasses by using thicker glass.

Is it a sign I drink too much beer that I can tell a 2 ounce difference between glasses???

Ahhh, but these lines aren't volume lines, they are alcohol content lines, this means you'd need a different set of glasses for each proof of alcohol served.

And if followed to the letter, each mixed drink would require its own unique set of lines depending on how heavy or light the bartender's hand is on a particular pour.
