any of our UK posters call their home lavatories WCs, or is that name reserved for public conveniences?Doug,
In my experience no-one
ever talks about WCs, even regarding public toilets.
Jo mentioned earlier that
her generation would call home lavatories
loos. Well, I must be her generation, and not the mere stripling I thought myself

.
But for public toilets you'd ask a stranger:
"Excuse me, are there any toilets near here?" (usually accompanied by a pained look and unusual gait)
Whereas you'd ask an acquaintance:
"Are there any loos nearby?"
or
very familiarly:
"I'm dying for the bog, mate"

Yet most of the
signs say WC.
The Brits are nothing if not consistent.
