George is driving fast into the advertised garden party. Ted seems to think that bunting and balloons to advertise your own garden party is a little low-brow and prefers a simple large sign. It would seem that Ted has under sold the garden party to his select friends and is hoping for some drop ins. He is advertising it akin to a Car boot sale or Farmer's Market. It seems a little foolish; anyone could come in and eat his sandwiches and drink his Cava.
Ted is a self-employed man who has come into some money. His business, that he owns, is going through a significant purple patch which has enabled him to not only throw a lavish garden party open to members of the public, but also buy a brand new house. Well done Ted. However he has neglected to employ any sort of valet system for the guests' cars. George has noticed this but as he is late, and thus he was driving fast, he decides to just park anywhere. He is in danger of driving straight into the revellers and gets very close. But he decides that the patio is the best place for his BMW.
Finally let us gaze at George's BMW. Business must be good for him too as he has a personalised number plate. The number plate reads 7 BPF. What could it possibly mean? 7 Beats Per Furlong? 7 British Pounds Fine? Or it could just be the cheapest plate he could find.
