Would not let me in with a backpack with a packet of chips when I told the Security at the gate one packet of chips was not a security risk? The security then told me the event organisers don't want any king of food bought into convention centre I said why not? The security said so they can make money out of people by selling food to them! I refused to go in saying this is an outright SCAM! By targeting people coming to see a Basketball Games! Then selling them massively overpriced food to their captive audience! What a Scam! Not sure how people put up with being Fleeced like this!
