Why we bother to put up signs I don't know.

We're getting ready to have an author in signing their book. We have a little area with a table and a comfy chair set up for him. There is a sign taped to the chair with the details of the signing which starts in less than half an hour.

A lady comes in and takes the sign off the chair and sits down with her coffee.

Co-worker: Excuse me, I'm sorry but can I get you to please move over to one of these other seats? This one is reserved for the author who is coming to sign in a few minutes.
Cust: Oh. Sorry I didn't realise.
Co-worker: (confused) but you moved the reserved sign that was taped to the chair?
Cust: Oh, is that what it was? I didn't actually READ it.


Yup. My forehead is starting to make a dent in my desk.

Do I look Untrustworthy?

Cust: I have a book in, you guys called me.
Me: Oh ya, right here.
Cust: But I ordered two books.
Me: It looks we're still waiting on one.
Cust: But I ordered them at the same time.
Me: Sometimes that happens. Especially if they come from different publishers. We can wait to call until everything is in if you prefer. We usually like to let you know as soon as something is in in-case you needed it.
Cust: Fine. I'll this one then.
Me: We'll call you and let you know as soon a the other one arrives.

No problem right? Fairly standard customer interaction? Yup. Until a few minutes later she goes through the entire thing AGAIN with a co-worker.
I guess she didn't believe me?
