Back in the days when we got plastic shopping bags, I considered it an art form to see if I could get an entire trunk load of groceries into the house in a single trip. Without squishing the bread.

You can get a lot of bags on your arms, and one or two jugs of milk in each hand depending on how long your fingers are.

It just isn't as fun with the reusable folding bags. Or the paper bags some retailers use -- the ones with handles are the worst, they rip a good part of the time. Actually easier to carry a normal paper bag than one with handles.
