Yuck! No. I suppose it's fine if you live alone, but not when you live with other people. I've never had to lecture anyone else about it though. My husband knows better and the kids are too small to lift the carton.
WE never buy juice in cartons, only in the 2 litre plastic bottles. As I'm the only 1 who uses them, I do occasionally take a drink, but only if I'm really really thirsty. The rest of time, I just use it on my muslin, in the mornings.
