full house, I win ?

So its Saturday, I'm at work, out the front and its packed, and its been that way for well over an hour now. Which is great for business, but not so great for my sanity.
However in saying that, the stupidity level has been pretty low so far, until my most recent customer.

So this woman and her partner come into use a machine, that's fine I put her on one of the few free machines i have, which coincidentally happens to be the machine right in front of me...
She was on for a few minutes before asking for some help.

Her: "Excuse me could you help me, I cant seem to access my gmail"
Me: "Sure, what exactly seems to be wrong ?"
Her: "Well I logged in, and normally on my laptop it takes me straight to my in-box, it doesn't seem to have done that"
Me: "Have you tried clicking inbox?"

Now by this stage I'm staring at her monitor frowning, she wasn't even close to having gmail on her screen, she did however have Google earth on it.

Me: "Yea I'm not surprised you can't access your mail, you have Google earth going and not the web browser"
Her: "Oh that was already open from when I got on the machine"
Me: "????? sure..."
Her: "I'm just used to using my mac at home"
Me: "Well there's ya problem right there"

She didn't appreciate that comment, but then I don't appreciate being lied to and having my time wasted, so i guess were even on that one.
