And how is 568ml just right and 500ml too small? The difference is just over 10%.
I think the difficulty is psychological in how many people (in UK I grant you- but I've heard similar complaints from germans) approach drinking. Generally when you get a beer, you have a good drink of it to start and then slowly drink off the rest of it and then when it's nearly finished you polish off the final 2 cm in one go.
The loss of that 10% interferes with the middle "grazing" period of drinking. You have the first glug, then a couple of sips later, you finish it off. Gone in seemingly no time. keep to the Fen Causeway
That's ridiculous. Inches are divided in powers of 2, but with the metric system you just add one more decimal place. So, any multiple of 100ml is an acceptable option at that level of tolerance. If you need a tighter fit, multiples of 10ml...
I don't think I have a single half-litre or full-litre glass at home and I live in metric-land. Plus, in Spain a customary measure for beer is a third of a litre (tercio, probably something like 330ml), which is also the standard measure of aluminum cans and small bottles.

The rest is just a matter of what you're used to.
Can't think of one in Amsterdam it'd apply to but I'm sure that's the reason keep to the Fen Causeway
