try checking the dates before you buy, and less of the slander regarding the cloning, it all bull s*it. It hasn't happened since a few years ago, i know!
It was at 0630 and the guy was just putting the milk out, you dont expect things like this to be out of date.
If they were just putting it out then of course you don't but I will always check the BBD before buying anything.
Not sure if anyone else is like me but if in Morrisons etc I will always reach to the very back first to check date as remember that when they restock they will put the latest date t the back so that people just take the first on the shelf.
Maybe that's my OCD kicking in but if I can get a extra 2 days freshness out of it then I will.
