Milk drought

I'm now regretting my choice to leave Tescos yesterday without finishing off my shop. I've just realised that I don't have enough milk left to make some Green N Blacks hot chocolate - gutted! Let's look at what we're faced with here. Why, oh why, would I want to go to Tescos when it's rammed with screaming kids piling lots of shite into their trollies? And what's the point of being open 24 hours if your fresh fruit and veg is only available between 8am-6pm?! Surely that defeats the whole purpose of a 24 hour "convenience" store?!
