The things I do...

So here I am at work, working, and of course Ive just had another stupid customer.
this customer, as hard as she was trying to not be dumb just couldnt help herself from failing....
So she wanted me to scan her passport, which I did, no problems, i scanned it, composed it into a PDF file and sent it to the machine she was on, now this is where things go down hill.
I get down to her with her passport and inform her the scanning is in my documents, no prob, she then turns to me and this happens

Me: "All righty, ya scans are in my documents and heres ya passport"
Her: "Oh where is it"
me: "My documents......"
Her: "OK so how can you attach it"
Me: "Do you not know how to attach files to emails ?"
Her: "oh yes I know...."
Me: "well then just the normal way, do a new email, attach the file and thats pretty much it"
Her: "OK, so how do YOU attach it"
Me: "excuse me ? you want me to attach it ?"
Her: "Oh yes.."
Me: "ummmm no, I'm not doing that for you"
Her: "Then how am i meant to attach it?"
Me: "???????? you said you know how to attach files to new emails"
Her: "I do"
Me: "Then uhhhh just do that, it'll be fine, send it to yourself and it will be in your email"
Her: "Oh how do you do that?"

At this stage, I gave up and just walked away, muttering that she needed to do a new email and just attach the files, I wasn't about to waste anymore of my time on someone with that limited a brain capacity.
