Over 10 years ago, a local radio station were talking about mcDonalds drive through and asked if anyone had been through on a horse. A girl I worked with rang them up and said she would do it.
She boxed her horse, unloaded it round the corner and rode through the drive through. I seem to remember they played it live on the radio, with the hooves clip clopping etc, they interviewed her and paid for her food too I think. Very funny at the time...
