Can't you let us have a nice cup of tea on a Saturday morning?

Why is it that the makers of milk, ok, not the cows but the companies that package and sell milk decide to make it go off on a Friday?

For some reason, every bottle of milk we buy has a best before date, or a use by date of a Friday.

This means that every Saturday morning I wake up and go to make a cup of tea for myself and my wife and the milk has gone off.

Some weeks we plan ahead and it's not an issue but when we do forget it is extremely annoying!

The milk in the fridge goes off on the 8th of January according to the label. That is this Friday so I either have to get to the shop before then to buy a bottle of milk, or forget about it and then get really annoyed on Saturday morning!

Why can't they just leave it in the cow for an extra couple of days so it doesn't go off until the Monday? That way, when we go shopping at the weekend, we can stock up for the week ahead.
