me, the manipulator

So I went to the grocery store this afternoon to buy ingredients for homemade spaghetti and meatballs. (Don't you wish you were here???)

I bought my products, walked to the bank to make a deposit, and drove home.
About an hour later I am cooking away and the recipe says, add ground beef... I look around and I can't find it anywhere! I walk out to the car, just to make sure I didn't leave it in the car.
So then I found my receipt and call the store. At this point I am so mad at the cashier. She wasn't friendly and careful. It's her fault my grocers didn't all make it home.
So the man answers, I explain my predicament...he puts me on hold...2 minutes later he gets back on the phone. "I am sorry, we don't have the meat, it's not here." (He says it in a way like he doesn't believe me...or like I need to check my house again." I say, "Ok, but I don't have the meat, what should I do." "Well, you can bring in your receipt and we will get you what you need." By this point I am mad at him. He is treating me like a liar. So I check my car again, come back inside, turn off the stove, and go to the checkout line I was in earlier. The girl says, "You're here for the meat aren't you? It's over there in the cooler." So they're both there....the cashier and the phone answerer. And really I am not mad at either one since they're both in my presence....but if it had been him alone I might have mentioned she wasn't careful nor friendly...and if she had been alone, I might have mentioned he was rude on the phone and thanked her for saving the meat.
There isn't much to say about my actual reaction. But inside I was burning up. I was so angry and I was thinking of all the ways to manipulate the situation so that I had no fault...I wanted to place all the blame on everyone else.

I left the store feeling ashamed.
