Question

I have a question about whether or not you guys think I gave bad service. This woman seemed genuinely convinced that I was just outright rude to her. I want your opinion.

She came in, and I noticed she was illegally parked in a handicapped spot. Our handi-spots are sort of difficult to see (we have clingy window signs in front of them because they are right in front of the store, not big old noticeable signs), and since it is against company policy to allow anyone to park illegally in a handi-spot at any time, I politely spoke up.

Me: Oh, you're parked in a handicapped spot.
Her: I'm just getting some coffee.
Me: Okay, well just so you know it's handicapped for next time, so you don't park there.
Her: Okay.

And then she started toward the coffee, then suddenly stormed out. She came back in a moment later.

Her: Just so you know, there is nothing out there telling me it is a handicapped spot.
Me: Oh, there is a sign on the window, and the paint on the spot itself.
Her: Oh... I see, it's behind me. Well you didn't have to say it so rude!
Me: I'm sorry? I wasn't meaning to be rude...
Her: (cutting me off angrilly) Well you said it REALLY RUDE!

And then she left in a huff... and I just kind of stood there. Do you guys think I was rude? Perhaps I phrased it rudely? I have no idea... I really just wanted to make her aware that the spot she was in was handi so she would know in the future. I didn't demand she move OMGNOW or refuse to serve her... I don't get it. But I'd like your opinions anyway.
