Thanks folks, just keep up the pressure!
When the new cafe was built, included, to one side are two large external bin storage areas enclosed by wooden panelling designed to fit in with the the rest of the building. You can find them on the right as you walk around the end.
That's the reason I got so annoyed. If there was no provision for waste fair do's but there is. It is the sheer reluctance of the cafe propriator to use them that galls me
