Court out by a Mango

Following the attention that ambush marketing has recently been receiving, both in this blog and elsewhere, I received the following e-mail over the weekend: "I had centre court tickets for [Wimbledon] last week. Get off tube at Southfields and pick up all the usual freebies on the 15 min walk up Wimbledon Park Rd. Have bottle of Evian and a fizzy drink in a can 'Rubicon' Mango I think. When they check my bag at the entrance - I'm told I can take the Evian in (official sponsor) but can't take the Rubicon into the ground. I either have to drink it before entering (which I did) or dispose of it - there were piles of Ribena, Mars bars (I think) and cans of Rubicon where people had just left them. When I question it, I'm told 'ambush marketing'. Just how mad is this? These guys can't start telling me what I can / can't take into an arena? This belongs in a totalitarian state; my guess would be that some of this stuff must contravene Human Rights law." Is this true? Is sport heading for confrontation if it continues to adopt a zero-tolerance approach to 'policing' what event managers and sponsors perceive as being ambushing attempts? Or are ambush police now behaving disproportionately? Are such actions justifiable and necessary, or are they now becoming entirely reprehensible? And how long before a human rights group, lawyer, consumer protection group or another similar organisation, take matters into their own hands, and how will/should sport and its sponsors react to this?
