They have bags. They are in a shelf under the checkout belt. If you want to bag your groceries, you buy the bags along with the groceries for 10 or 12 cents. You can also take corrugated boxes in which their dry goods were shipped, free, from a large wire crate and use them to take your groceries home, and then set them out to hold your recycling for pick up so you don't have to set out a plastic recycling bin and go take it back again. Win-win.
Once you get used to the ways Aldi cuts prices by being “semi-warehouse,” it's a great store with prices 1/3 to 1/2 less than comparables at larger chains. It can even beat the Sam's or Costco prices on many items if you don't mind comparing. I keep a running list of my regular items in my phone at which store so I can check which is the better deal.
Not all their store brands are as good as name brands, but some are just as good and many are better, and at lower prices. They also have great specials. I got a tree lopper for $9 at Aldi that sells for $20 at Home Depot. Same with many other useful items.
The German thing—still reliving WW2? Germany and Japan have been U.S. allies for some time now.

Beware of roaches hooking a ride on cardboard boxes. We think that’s how dem roaches got into our kitchen.
