Gripe

It's been a long time since I've whined about customers. Apparently someone noticed the lack because they decided to be especially obnoxious just to inspire me. Well, I can't really say that sort of thing anymore. I thought it was all about me, but it may actually be all about them.
So I get called for a carry-out and this gray-haired woman tells me she needs a couple of bags of fertilizer and three bags of bird seed.
On it.
While she goes on ahead to her car, I grab a cart and then wheel it to the pile of fertilizer. One, two. Then I go to the bird seed. Three 20 pound bags later, I turn around and hunt for her. Is that her? Nope, driving away. Ah, that must be her by the black car. So I wheel the cart to the black car.
She looks at the cart, somehow dissatisfied. "I forgot my garbage bags at home. Can you put the bird seed bags down first? They don't look too bad."
Ah, dirty bags. NP. I load in the bird seed, put the fertilizer carefully on top of them, and go back. But wait! There are a couple of extra carts, and there's some dirt that needs to be upstacked. So I do that, and then head back to the store.
Who do I run into on my way in? The lady.
"I wanted you to know that I complained."
????
"I went back and checked and those bags of fertilizer were the dirtiest of all of them."
"I'm sorry. I just grabbed the ones on top."
"I could see putting them in the back of a pickup truck," she said, apparently not realizing that I had no idea what kind of vehicle she drove in, and if she cared so much, why the hell was she picking up fertilizer in it? "But not in my nice car."
"I'm sorry," I say again, feeling slightly less sorry.
"I just wanted you to know I complained."
"I'm sorry," I say, when I really wanted to say well I guess you'll just have to have your slave vacuum out the trunk of your car for you. Oh, but wait, you won't ask them to do that. They have to magically know that it's not up to your standards.
"You should have someone come out here and wipe down all those bags," she added.
What. The. F ... never mind. "Okay," I said. Neither myself, nor anyone else in the store is going to come out here and wipe down every bag of fertilizer and every bag of dirt so that no one else will have this horrible experience that you've had. Oh, wait, you're the only one who cares who brought their 'nice' car to pick up fertilizer. Btw, if she'd asked if I could bring her a plastic bag, I would have. I could have also swept the dirt off with my gloves. But no. She let me load them up and then complained.
Also btw, I went back and checked. I should have given her the two bags with fertilizer caked on the outside of them in addition to the dirt, rather than the ones that had dust and bits of leaves. Those two were not in fact the dirtiest.
Missed opportunity. Next time I'll have to pay attention to which bags I snag.
