I went into the wine shop down the road last night, walked up to the counter (careful not to let Boy touch any of the Expensive Things) and waited for someone to realise we were there.
We waited for a few more minutes.
Then a few more. It's not unusual for the owner to be round the corner filling up someone's car with wine, or having a chat with someone outside the nearest coffee shop.
Eventually, I turned towards the door at the back of the shop and said (loudly): "Bonsoir!"
Then, after a moment or two more, slunk out of the shop, empty handed, a little guilty that I had looked in the corners for the non-existent CCTV cameras.
