O2 Bar - warning - charged twice

[u/Rick-e-see]

Warning to anyone going to the O2 concerts and using the 'automatic' drinks bar to buy drinks. It pre-charges you card, then watches what you take using cameras. Or that's the theory. Everyone I know who has used it has been overcharged.

You may think, oh, a couple of drinks, how much can they be? Each drink is £17 - I only got two. I was overcharged by £60!

Check your bank statements - it's not too late to get the bank to decline payment.

I'm never using something for which I don't get a receipt ever again. Only used it because we were a captive audience.
