To object to paying 50p extra for a "large" cup of herbal tea, when all I'm getting is a weeny bit more hot water?

I probably am, because the menu was on the counter, so perhaps instead of allowing the "selling up" I should have picked up the menu and queried the price.

BUT
Regular latte: 1.20
Large latte: 1.55

Regular herbal tea: 1.10
Large herbal tea: 1.60

WTF?

fair enough but from my interpretation the price was clear as it was freely available.
if you order something without asking the price or checking the menu to see what the price is i don't think you can really complain that you were taken for a ride or that the price was not clear as you made absolutely no effort to find out the cost.

theBOD - you're quite right, legally speaking I have no cause for complain - but why should that deny me the right to tell them that their pricing was bonkers? Which, in fact, was exactly what I did. I did not actually ask for a refund, which I wouldn't have been entitled to, BUT I am very surprised that they didn't offer me one, just to keep my custom - in which case, I would have put it straight into the charity box.

The most annoying thing, is that she COULD NOT SEE my point about the fact that my cheaper-than-latte-when-regular-drink became a dearer-than-latte-when-large-drink.

As I told the woman there, I'm a deep-pocketed Yorkshire lass who likes value for money - and what I got was clearly NOT value for money.
