When's A Cafe Not A Cafe

I passed a new roadside cafe.

It was a converted container on a recently graded bit of ground.

The rumour is that it is only there six days a week. On the seventh it has to be put onto the back of a truck and taken somewhere else. I suspect this is to satisfy the criteria that it is a temporary and moveable structure.

Brilliant.

It is a natural progression from those billboards tou see in fields next to motorways. You will see they are always mounted onto redundant articulated trailers or farm vehicles. All however will have wheels - meaning that they are mobile, therefore temporary.

I'm sure this trend will continue. Any ideas for any other businesses which could go down the same route? If so post a comment.
