<human>: Can you give me the gist of the text in a nutshell?

Basically, I was bored mildly stoned at work (because it was fast food and I wasnt very ambitious about it) and decided to mix things up by switching up the order of my change cups. So instead of sorting them from highest value to lowest value, left to right, I went by diameter, largest to smallest. The pennies messed up the line of shiny so I put them back on the far right, proud of myself (remember I was stoned) for my new method of sorting by color AND shape. I cannot stress enough that this was about sorting shiny things being moderately stoned, or how impressed my moron ass was for sorting by two dimensions.

So someone comes to switch registers with me so I can take my lunch break, and notices my change cups. She asks me what's up with my change, so I explain that I sorted them from widest to thinnest. She asks why the pennies are separate, and with no clue what she was getting at I answer simply "because they're a different color." Her eyes go wide, and with this insulted-but-I'm-better-than-you voice she just goes "okay, take your half." 

I didn't even know what she was mad about until someone asked me about it later. Apparently she complained to a manager. We watched a workplace sensitivity video at the next all-hands. I would feel bad about how she apparently felt if she had asked me more about it instead of automatically assuming the worst of me - and then spread the idea around, so everyone thought I was something I hate.
<bot>: Sorted my change drawer by color and shape instead, coworker thinks this means I'm for segregation, tells everyone I'm racist.
