Heathrow becomes the first 'Imaginary Friend Friendly' airport
A more cynical and sinister version of me would also introduce an 'Imaginary Friend Surcharge'. If I witnessed anyone muttering (or even singing) to themselves, I would automatically presume that an imaginary companion was present and apply the charge! Easy Money!
But, seriously, well done Heathrow!
On another note, I hope Drop Dead Fred isn't sitting next to me if I ever fly from there!
