All I can think of when I see this is the bigger bag, that had like 3 or 4 1L bags of milk in it that this one time fell out of their grocery bag in my parents car and 2 of the bag got sliced open. The smell never left the car despite major efforts to clean up. I hazard to guess this is a big reason they no longer come in bags, but I hear maybe they still too in central Canada. Not here in the west.
I hated that scary moment when the big bag of milk bags fell open unexpectedly.
The tension that I'd feel after dropping the bags was immense. It was like time slowed while waiting to see if one of them would burst. It was freakier when one of the falling bags bounced off the floor. Fun times.
