So I don't forget them I put them back in the car as soon as I put the groceries away. It takes no time at all. I grab my purse when I get out of the car. How much more time would a couple of cloth bags take? Two seconds. I always feel guilty when I have forgotten my cloth bags and have to ask for paper.
I don't like to use plastic grocery bags. Our local Jewel has a bin for "recycling" but I know a lot of people who work there and they said, "We don't recycle them. We take them out of the bin and put them in the dumpster. It's just to make people feel better that we even have the "recycling" bin at the door." The ONLY thing I ever let them use plastic bags for is raw chicken. They always start bagging, like 3 things to a plastic bag, then I give them my bags. They usually try to just put the plastic bags into the cloth. Now, WHO is that helping. I make it clear I use the cloth bags to AVOID plastic. Then, if they don't do it, I take my stuff out of the plastic and toss the plastic bags back on the counter.
You'd think most of the checkers and baggers would get it by now! Some of them do, and they ask. But, a few of them are just.... lazy and don't care.
