<human>: I currently work in retail at a grocery store (hopefully not for too much longer). I frequently get asked about the location of items or if there are anymore of a particular item in the back when we are out on the shelf. Almost every time I am asked I am more than happy to stop what I am doing to help the customer, because after all that is my job. Only rarely does a customer act in a manner that really upsets me, however on this day one customer did, and she felt my petty wrath! A few weeks ago some rude lady comes in and asks me in a less than friendly manner, "Where is your Parmesan at?". I take her to the cheese section of the fridge where I notice the bagged Parmesan is out, though we still have tubs of it at the exact same price by volume. I show her this and she says "no I want it bagged, go to the back and get me some bagged Parmesan!" I am really upset at being treated so poorly, and to make it better we do not have any in the back, since our next shipment will not come in until next day. I tell her that I am sorry but we have no more in the back so she gets mad and says that it is unacceptable and that she cannot believe I could not find any. As she turns to walk away it hits me...we have some in our organic section. Unfortunately I might have forgot to mention this to her as knowing she would have to go to a different store or wait until the next day made me feel much better about her bad attitude.

Can you give me the gist of the text in a nutshell?
<bot>: A customer treats me like dirt and so I do not find the product she was looking for so she has to go somewhere else to get it.
