From MetaFilter. The poster’s description is succinct but accurate:

McDonald’s UK goes Web 2.0 with a site answering user’s questions. Apparently, all of them.

Some of the questions are silly:

Why did my banana milkshake turn bright orange after a few hours stored in the fridge?
[They didn’t know]

Why do I get the Spurlock McGurgles everytime I eat at your resturants?
McDonald’s is not aware of the ‘Spurlock McGurgles’ as being a specific phenomenon. Everyone has a different digestive rate and can be affected in different ways by the things that they eat.

Some are cultural:

Why doesnt England do the Shamrock Shake? We celebrate St.Patricks day too!

McDonald’s feels that the Shamrock Shake would not be as popular outside of Ireland. [I hadn’t realized I was living in Ireland.]

Some are poignent:

How do interest rates (rising and falling) affect McDonald’s?
As with any business, interest rate changes affect McDonald’s. McDonald’s globally is predominantly a franchised business and franchisees will often finance the purchase of a McDonald’s restaurant through a bank or other lender. This loan is set at a fixed rate, above the country’s base rate, and consequently, as the base rate rises and falls so too will the cost of the financing. Here in the UK, the Bank of England sets the base rate. This is currently 5 percent (November 2006). This will impact those franchised restaurants where a loan is still outstanding. Company-owned restaurants are not affected by movements in the UK base rate as they are funded by the US and so will be subject to variations in US interest rates.

Wow, that’s almost a real answer.

Many are political:

Do your farmers use any Genetically Modified animal feed? Do you use any Genetically Modified ingredients? Is is possible to have a personalised answer which actually answers my questions instead of the usual “we value your comment”?
McDonald’s does not use any does not use any genetically modified (GM) ingredients in the food it serves.

Notice that McDonald’s answered the second question, but not the first (or, for that matter, the third).

Have you stopped poisoning people?
McDonald’s is a legitimate business and sells food and drink acting fully within the laws of the countries where it operates.

Still, not answering the question.

My question: What on earth did you do to the poor animal to make your chicken sandwich so vile? And more McRib, please.
