We sat down in the restaurant and promptly handed our Groupon voucher over to the girl.
"Do you know what the voucher includes?"
"Um, sort of"
"Well it's 3 courses from the A La Carte menu and a glass of Prosecco each"
"Oh right, well can I swap my glass of Prosecco for a diet coke instead please [raises hand] non-drinking driver here"
"Oh, um, right [turns to Gordon] unless you want both glasses of Proescco because a diet coke is only £1.50?"
"No, that's fine, we'll have a diet coke instead please"
