I go to Walmart mainly for prescriptions because they are one of the few places that doesn't gouge me and my insurance company. (In fact, I pay outright for 2 of them, since it's cheaper that way.) Of course, they get me for other stuff, since I will shop while waiting for a prescription to be filled.
Anyway, a month ago, I bought some things there and I had my permanent Trader Joe's bag with me. It fits nicely in my bike basket and is good for a small load of groceries. As I went through the check-out, the clerk started throwing my items in a plastic bag. I said, "I don't want that bag. I already have a bag." Then I showed her mine. She gave me a dirty look, pulled the items out of the plastic bag, and then threw the plastic bag in the trash.
I went to customer service to complain about this. I explained that there was no point in me bringing a bag if the clerk was going to throw a basically unused bag in the trash. They said that the bags are recycled, they don't waste, etc. (To me, spending the energy to recycle an un-used bag is wasteful, but que sera.)
Today, I when I bought meds and groceries, I put the Trader Joe's bag first on the conveyor belt, so the clerk wouldn't make the mistake of bagging the stuff in plastic. ...So she bags my first two items in plastic before I catch her, and then says, "There's no price tag on this" (about my bag) and "I'll have to get price check." I tell her that it was purchased elsewhere to carry groceries, so that I can save a plastic bag. I have to tell her this twice. Then she takes the items that she had already placed in a plastic bag(still in the bag), and puts them in the permanent bag.
I say, "That kind of defeats the purpose. I brought my own bag so you wouldn't have to use one more bag."
Then there were a few items (chips) that wouldn't fit, and I told her that I could deal with one bag that would hang off the handlebars on my bike. So she double bags them. WTF???
I wasted more petroleum on that trip than I saved by riding 1/2 mile.
