Sorry for being so vague, but I half remember a scene in a play on, I think, the BBC in about 1980 ish, where a middle aged couple had gone on holiday and a group of young guys and a girl were having a bit of a laugh around the swimming pool, and the girl got thrown in, fully clothed, in a summer dress and heels.

The middle aged woman thought it was funny, but her husband was a grumpy sod and didn't.

Anyone ever heard of it?

Sounds like a nice scene!
