The venue bars/restaurants are staffed by people who couldn't work slower if they tried. No sense of urgency to get people, who have paid a fortune for tickets including a ridiculous venue supplement, served so that they can watch what they've gone to see. The bars also regularly have problems with the drinks they serve on tap so you can't even get the over-priced drink you wanted. Consistently disappointed by the O2. Really not sure how it justifies charging so much for such awful customer service.
