I don't know where you live, but I've been going to Aldi for years. There are two stores in my immediate area, and I can't really recall seeing any "low-class" people - especially considering that one of the stores is in an upper-middle class town. You don't pay for the cart, you "rent" it. Putting a quarter in gives people the incentive to return the carts to the stalls to get their .25 back, instead of leaving them all over the parking lot (some regular stores in my area do that too). Not having baggers cuts down on costs, which trickles down to the consumer, so you're encouraged to bring your own. If not, you can buy some for cheap. Big deal. I shop there bc I eat a lot of produce, and theirs is brought in fresh every day, they have great prices on organics, and since it's a German company, I have access to my favorite European snacks. I love it.
