Developing Alzheimers?

I was telling my girlfriend a story about how I thought I was a victim of racism when I was in Chicago. Basically, I went into a Walgreens to buy some stuff before getting on the plane back to Seattle. The store clerk was helping the customer in front of me, and I was just kind of looking around the store. She asked, "Can I help you with something?". I said, "No, just waiting to pay for my stuff". And didn't think anything of it.

I proceeded to pay, the bill came out to about $3.00, which I charged to my Amex. She asked me for my billing zip and I told her 08544. She said it wasn't working, and asked me again. I repeated, 08544. She said it didn't work. I was in disbelief, as there is no way my card is getting rejected for $3. But instead of figuring it out, I just paid in cash. Later that hour, I stopped by the gas station to get gas and my card worked just fine.

Like I said, I relayed the story to my girlfriend that night and was sure that the woman was up to something funny. I told the story EXACTLY like I did above. And then it dawned on me (much like it has already on Jenny) when my girlfriend looked at me funny. My zip code is not 08544, and it hasn't been in over 7 years.
