You've bought some corporate tickets for a premier football match, but you turn up to find you're in a marquee in a car park, five miles from the ground. It's a problem that the Corporate Events Association warns isn't uncommon in the industry ­ black market companies offering and often not delivering tickets, or scraping together packages which don't cut the mustard. At any event at Twickenham, there can be 6,500 invited corporate guests and between 5,000 and 10,000 unofficial ones. Companies like Peter Parfitt negotiate to become officially appointed so they can get official ticket allocations and say these black market companies give legitimate firms a bad name. "It's not illegal," acknowledges Neil MacLaurin, "but it must be dreadful when you've spent a lot of money. However, when bad publicity hits the papers about people not getting seats it's good news for us because they want to go with someone they know they can trust." He advises people offered packages to quiz the firms carefully. "Ask if they're officially appointed, and where your seats are in the stadium. If in doubt, ring the sporting venue and check." The CEA's Tony Barnard adds: "Black market sales still go on ­ we strongly advise people to book from a CEA-approved member." {{FEATURES }}
