Re DC's comment .....

I saw an old work colleague in my local supermarket a few years ago, 100 miles from where we worked and he and his wife were visiting here on holiday. I invited them round for G&T's as they were going on to dinner at a restaurant near me. I had an unopened bottle of Bombay Sapphire and when I got it out of the cupboard I was cross because there was only about a third left so I was cursing my student lodger - he had had a party at mine when I was away at a conference, without telling me, and I came back to find a box of broken antique plates and a beer can dripping into my TV set. He got notice to find alternative accommodation.
Anyway, I poured out our gins, probably a double each, and then we had another. I couldn't understand why I and they were feeling rather drunk after that; when they went to go the man fell out of my front door! They said they were too drunk to go to dinner! I looked at the bottle later and found a pin prick hole in the corner of the cap. It had been in my cupboard for years so I realised that it must have evaporated over time, leaving very concentrated alcohol!

I don't know if they ever came down here again, but they never called round again for a drink - they must have thought I was dangerous! 🤭 😄
