Why have almost all the burger kings in Greater London closed down?

Question

All the Burger Kings around where I live have closed down. Places include Hounslow, Greenford, Southall, Feltham and Hayes to name a few, can anyone explain why they have closed so suddenly?

Answer 1

Because consumers are a lot more switched on these days and have realised that they need to eat more healthily and not eat the rubbish you get in Burger Bars, hence they have to close down.

Answer 2

Because of Mad Cow disease???
