To expect supermarket milk not to be lumpy by the next day?

[GreenPenguin]

Grrrr. 6.45am, dark, raining, hungry toddler, etc.

no yanbu.
Once my toddler who was about 18mo drank a whole bottle of off milk as she would only drink milk at room temperature. She didn't care but we were nearly sick when we realised..

It was quite stomach churning, girlsyearapart!
As well as the pain in the arse this morning, there's the whole - we give the supermarkets £100s, we queue for ages for the privelege, etc etc.

this happened to me once and i was fuming til i realised i had turned the fridge down by accident are u sure your fridge is cold enough?
also, it happened another time and i was again fuming until dp said 'oh i didn't think it would matter' me:'what wouldn't matter?' dp:'well i left the milk out for a few hours last night, i just forgot about it, didn't think it would matter!' me:'WELL IT BLOODY WELL DOES MATTER!'
