Before anyone gets their hopes up, it wasn't that kind of adult-only
On holiday a few weeks ago we were wandering around looking for somewhere nice to get a jammy scone (as you do) & spotted what looked like a nice wee tea shop. We checked out the menu in the window - looked good - & were just about to go in with 3yo dd & 17mo ds when I spotted, right at the bottom, some guff about being pleased to provide a relaxed & friendly adult-only atmosphere.
I have to admit I was gob-smacked & highly miffed. I was all for pretending I hadn't noticed the adult-only bit & going in with the DCs just to see if they'd chuck us back out again but dh wouldn't let me.
This was a very popular wee coastal village not far from Edinburgh & it gets a lot of foreign visitors - it's no wonder a lot of people think the British aren't child-friendly!
