The McDonald's sponsorship deal at the Security Games in London meant that Olympic workers are not allowed to buy chips (AKA fries) unless they come with fish. A chorus of complaints from site workers has led to a relaxation of the sponsorship terms so that workers (but not visitors) can buy their chips from the vendor of their choice, even if they're not served with fish.
From The Guardian's Robert Booth:
It all results from one of the stranger twists of Olympic planning. McDonald's sponsorship deal included the exclusive right to sell chips in and around Olympic venues. Other caterers had negotiated special rights to serve chips with fish – but not chips on their own, or with anything else.
Cue frustrated scenes at the lunch counter in the ceremonies catering area where staff were toiling over the staging for Danny Boyle's 27 July opening extravaganza. "Please understand this is not the decision of the staff who are serving up your meals who, given the choice, would gladly give it to you, however they are not allowed to," read a notice pinned up by staff. "Please do not give the staff grief, this will only lead to us removing fish and chips completely."
"It's sorted," said a spokesman for Locog. "We have spoken to McDonald's about it."
But the embargo will hold in other areas. That means no chips with anything other than fish anywhere else in the park unless spectators dine at McDonald's.
I know a couple of people on the lighting and automation crew at the Security Games and they report that there's a mass lunchtime exodus from the site by its workers every day as they troop off to find anything to eat that isn't McDonald's.
