I went to Patisserie Valerie recently, as my friend had become very chilled and we wanted to warm up. She chose soup, which fortunately arrived quite quickly and she thoroughly enjoyed. But there was no vegetarian soup available. So I waited patiently for my toasted sandwich … and waited … and waited. When I asked the waiter he retrieved it from the “dumb waiter”, where it had presumably been waiting nearly as long as me! It was, perhaps naturally, completely cold. He had it warmed up for me (re-warmed toasted sandwich?) but it was still cold. When our original waiter (who’d been on a break returned) returned he was very upset, and had a fresh one made for me. But by that time the episode was ruined.
“Must try harder!”
