How new is this as a policy? I tried to buy 3 cans of gin and tonic ( they're currently on offer at 3 for £6) and was told very snippliy by the woman at self checkout that I had to buy a snack to go with them.
I questioned it and she reiterated that I needed to buy some food, and was pointing at the chocolate bars by the tills.
I didn't need or want any food ( in fact I'd just eaten) so I put the cans back and deprived them of a sale.
I wasn't planning on chugging them one after the other on the train home, for gods sake -they were going in the fridge as I prefer ready mixed to home measures so I don't go too mad 
I asked another member of staff about it on my way out who said yes, it's the local council's policy. But the previous week I had bought wine at Sainsbury's two doors away with no problem and was unchallenged.
It's not the biggest deal in the world but it does seem a bit Nanny State-ist seeing as I could have gone to the pub opposite and drunk all night without eating anything!
Has anyone else had this or have I been living under a rock?
