I visited in summer of 2000 (I believe, I think it was summer after junior year in high school, but I could be off by a year). I remember when you went in there was a place where you typed your name into an iMac (an older model one, it wasn't the newest at the time), and a label maker printed out your name. It was a bit funky for such a large campus. We stood around the lobby for a while and you basically could not go anywhere except the gift shop. I was kind of a little adventurous at the time, and I stood around for a while and managed to catch a door after an Apple employee swiped their card. I called to my dad and told him we should go in and just say we got lost or confused if someone found us, but he thought it was a bad idea and I wasn't that adventurous after-all so I let the door shut. What could have been! We went into the gift shop. I remember they had knick-knacks and a few computers on display. It wasn't terribly exciting. We had had terrible luck with our Performa 5200 CD and my dad always was bitter that Apple never honored its commitments to that computer which had one problem after another so he somehow thought talking to the cashier at the Apple gift store was going to finally get him somewhere. He was half-joking, asking if he could mail it back to them at the campus. And I remember the cashier saying something like they didn't make good products back then and it was a dark time for Apple. It was interesting how honest she was about the time of Apple before Steve Jobs came back. In 2000, Apple was becoming exciting and getting its mojo back and I think even more exciting a company than it is now (though it wasn't the big juggernaut it is now). I must not have bought anything--I'm sure my parents said everything was too expensive. I remember afterward my dad being disappointed that they didn't have tours set up or anything and said that we should have snuck in when I had caught the door. I naively was hoping it would be like Disney where I got to go behind the scenes and watch some animators at work and they even showed sketches from upcoming films they were working on (that was when I was really young--I think at MGM).
So, I think that T-shirt would be more appropriate with the adage it borrows from, "I went to the Apple campus, and all I got was this lousy T-shirt." There's nothing to see there . . . unless you sneak in!
