From SEND_ME_YOUR_CAULK, Tales From Retail:

I work at a large clothing retailer, and sometimes we have online exclusive items. As the name would imply, they are online exclusive and we don't keep them in stock in the store unless it's been returned. The item this customer (C) is trying to return is six months old and still on the website.

C: Where is this item? It says on the website you have it

She shows me the webpage, and whenever I get shown a webpage, I immediately scroll up to see if it's online only.

Me: We don't carry this item in the store since it's an online only item and it's on the older side. I can enter the information and see if we have it.

C: Go check because I need it tomorrow.

I go and enter the products information in the item inventory (it gets updated constantly and has the quantity of every item)

Me: I entered the information and we don't have any. Sorry about that!

She puts her phone down, looks me dead in the eyes, and point-blank says:

C: You're lying to me. I know you are. It says you have it. So where is it?

Me: I'm sorry we d-

C: No, I don't want to hear it. You're lying. Show me where it is.

I try to turn the computer monitor around to show her and she says:

C: Do you really trust a computer over the website? It's probably a glitch anyways, now where do you keep them?

Before I can even respond, she walks away and starts shuffling through all of the wardrobers and racks violently for 3 minutes and then when she can't find it, attempts to walk in the employee room and then storms out.
