It's not good when...

the rain forces the mermaid to go home. It came down, and she (it) decided she'd (it'd) had enough.

Still, the festival tourists weren't put off - maybe she'd (it'd) claimed her (it's) horde for the day. By the looks of some of these buskers and street entertainers I reckon there's gotta be a quid or two to be made over a long lunch or an early finish to the day-job.
