Okay, this isn't quite in the same league as "Scones-gate" from a couple of months ago, but yesterday I went to our local coffee shop (we're in a small-ish market town in Kent) where they charged me £1.20 for a small cup of milk for DS (3yo). I completely gawped at her when she told me, but she didn't budge just kept saying "that's how much it is".
AIBU to object to forking out that much for what was about 100ml of milk, especially when they gave me a third of that amount free with my coffee anyway? Just felt really quite ripped off!
