He had a couple Urban Outfitters bags on hand and an entourage of four.
That's when I saw him. John Mayer. He started out looking at the iPad displays, not 6 inches from where I was standing. I saw him, turned around and whispered to my coworker "John Mayer is right behind me." Her eyes got big and she scanned the vicinity until she saw him. She about had a heart attack right there. We followed him around the store while a couple people asked him for photos and/or autographs. The Apple Store was packed (when is it not?) but most people sort of ignored him, save a few who asked for autographs/photos. We debated whether or not we cared about being "one of those people" right up until was saw him walking towards the door. Instincts turned on and I caught him on the way out and asked him for a photo. The conversation went something like this:
Me: Hi, John Mayer? (Why did I just call him by his full name? Total "I carried a watermelon?" moment)
John Mayer doesn't hear me.
Me: Hi. John? I'm so sorry to bother you when you're just trying to shop at the Apple Store. I hate people like me, but do you think we could get a photo?
John Mayer: Please don't hate yourself. Yeah, of course.
Me: Thank you so much. I just had to ask. We are going to your show tomorrow.
(we are not going to his show tomorrow)
John Mayer: Cool. Yeah, you just got to go for it sometimes.

Notes:
- John Mayer is a lot taller than I thought.
- He has a rather large head.
- He also looked hung over.
- This guy dated Jennifer Aniston? Really?
- I can't believe I met someone I follow on Twitter.
