It is quite possible to buy something quickly for a snack or a drink (on the road). It is clearly in its place. I wish there were more soft drinks in the fridge. I'm taking a point off just for that...
I do not recommend this point, especially any kind of baking. It's purely a lottery, lucky or not. And so if you have juice, a drink, some kind of chocolate bar that does not concern your own baking products, then please.
