The case has been made in multiple threads why customers choose certain vendors over others, and why most people would prefer other people mixing their juice than doing it themselves via DIY.
Everyone (everyone, it's not a new concept here at ECF) knows it's cheaper doing it DIY. But the vast majority prefer the vendors to do it for them. Like someone said, I can cook a steak at home, but I think I'd enjoy a finely prepared meal at a nice restaurant despite the extra $. You're paying not just for sustenance to survive, but the experience and the luxury to dine out.
