Your Friendly Walmart Pharmacy- Not so Much

I take three different medicines for a medical condition.  Until recently I was taking two expensive medicines that didn't work very well.  Lucky for me, my wonderful doctor listens and switched me back to the medicines that work.  Unfortunately, the least expensive pharmacy in this po-dunk town is Walmart. So my doctor called the scripts in on a Monday. I waited a whole week for them to find time to fill them. Ha!
I went in and was told that they hadn't even gotten to my order yet. I use a program called GoodRX that really lowers the cost of my prescriptions.  I went to the order window to see if by chance my order was ready.  They hadn't even started it!  So then, I am dealing with the antithesis of customer service as she snippily tells me all of the excuses reasons why my order hasn't been filled in the week since it was called in.
Then we get to the total.  I ask her why it was so much.  This paragon of rudeness tells me that one script isn't covered by GoodRx.com.   I said, "It would be cheaper at Walgreen's full price."
She haughtily told me, "Then you should go to Walgreen's then."
 I don't have my phone with me, I need the medicine, so I pay the price.  I go to my phone in the truck.  I pull up the medicine and the correct price.  I turn on my heel and back in I go.  I waited in line and asked her, Do you remember me?" She didn't.  I show her the price of my medicine.  She tells me I am wrong, then pulls it up on her computer (which I doubt she did the first time) and says sheepishly, "They must have just changed the price."  Yeah. That's what happened.  It wasn't that you were being a dick, ma'am and too stinking lazy to push seven buttons.  They OBVIOUSLY changed the price in the blink of an eye.  So anyway, I got the lower price and had to get a refund.  This is where the retarded (sorry Sarah Palin) stepped in to put the icing on the cake.  The change was something like $15.74, so I asked Forrest if she could give me a quarter if I give her an extra penny.  This is exactly what she said: "No. I can't do that.  Because I am kind of anal, I have to give you exactly what the machine says."
Maybe if she is so anal that she can't work change, I don't exactly want her back there doling out my pills.  What happens if she runs out of one kind and has to open a new bottle to finish my order?  Will that send her into a stupor?Will she be unable to function?  How will she manage?
Kroger and CVS both have pharmacies in this little town.  The hospital also has a pharmacy on their property.  There is a larger town not 20 minutes away from here.  Go there,  instead of this Walmart pharmacy.   You'll thank me later.
