One of my coworkers is a mustachian! I'll probably make a separate thread about how awesome it is. But here is how we recognized each other:
We were eating alone in the kitchen table area. She works in another department, but it's a small company, and her desk is pretty near mine. She's the only other person at work who bike commutes, and she's got a side hussle (teaching fitness classes).
She had a salad from a nearby restaurant (usually she makes her own spinach salads during lunch), and I was eating a healthy packed lunch. She commented on how my lunch looked delicious; I commented on how hers looked delicious as well. She stated that she was unhappy with the price, and stated the after tax price to the penny (I feel that most people don't pay attention to how much they spend on food). I agreed that it was over priced; I said that my lunches cost under $15 for the week, and that I liked keeping track because personal finance was a bit of a hobby of mine.
And that's when she asked if I read the MMM blog. And I was like, YES! We talked quietly a bit about how generally excessively lavish our coworkers are. It was like finding someone else in the matrix who also knows that it's all virtual reality.
