This reminds me of when I worked behind a bar. There was one customer who always drank Gordon's gin and refused any other particularly Squires Gin. One day we had run out of Gordon's gin and had refilled the bottle with Squires without telling the customers of course. The 'Gordon's man' came in and ordered a large gin. ''Gordon's, don't give me that Squires rubbish''
The manager poured him a large 'Gordons', all us staff knew it was Squires! As the manager handed it over he said '' here's your Gordon's Squire'' and winked at us.
'Mr Gordon's', drank his gin and said '' It's a great drop of gin that Gordon's not like that Squires rubbish''
We never told him , but he got several more ''Gordon's'' that were really Squires until the bottle ran out.
