Great team - decent venue - incompetent staff - expensive prices. Poor food n beverage options.

We took our boys for a family evening out to watch the London lions basketball team, £80 for tickets which cone with seat numbers. On arriving we asked to find our seats only to be informed by the ushers that we could "sit anywhere". THIS CAUSED CHAOS! initially it sounded good, but then inevitably we had later arrivals saying "we booked the seats you're in?!" To which we replied "we were told to sit anywhere", the poor family tried to find our old seats but saw they were also taken by other punters who'd been given the same awful advice. They came back to us after about an hour and pleaded to sit where they had purchased, I then relented (whilst still furious that it was the staff who had caused this issue) and moved my own family elsewhere, no doubt taking 4 other seats that someone else had reserved. It was a huge disappointment, and very unprofessional. I then when to get sone food and drink, and paid over £50 for 4 hotdogs and 4 drinks,(2 alcohol and 2 soft drinks), the rum and coke was a simple £1 250m can, but they were charging £6.90 for it! The queue was huge, and they clearly need more food and drink outlets in the venue. I then came back to finally sit down and watch some of the match which was good, and so was the halftime entertainment and running commentary. After half hour or so I went back to get a couple more drinks and found the queue to be about 50 people deep after waiting 20 mins and barely getting anywhere another useless member of the staff came by the queue telling is to "go up to the next level there's another bar up there's and it's empty" a few of us believed her (foolishly) and left our places in the queue to go upstairs, where we then found an even longer queue about 80 people deep. We were now stuck as we couldn't return to our old queue (only to rejoin at the back) and also didn't want to have to walk back into the arena with nothing having already waited about 25 mins by this stage. Most of us were raging at this point and felt completely helpless as we stood around waiting to pay for more overpriced rubbish. By the time I finally got back to my seat I managed to catch some of the 4th quarter and vowed never to come back until they get new staff and more bars. This could have been a really enjoyable day but the staff incompetence and unprofessional advice, pkus management prices/lack of bars ruined it. I'd spent over £150 been shuffled around from seat to seat, had to argue with innocent people, been misled and lied to by staff and waited in long queues to pay over the top prices.
