Who is an excellent provider who you would never ever guess is a provider if you met her outside the hobby?

Don't Hate the Question: I realize that some ladies/hobbyists will be unhappy with me for suggesting that there is some kind of stereotype for providers. There is nothing negative intended or implied by my question. Great Providers just like all people come in many shapes, colors and sizes. (just like hobbyists).

There are a lot of wonderful providers here. Some of these women are really terrific but once you meet her, have your initial impression, you realize that if you met her in the civilian world you would never guess, suspect or imagine that she is a provider. She is someone who if you worked beside her in an office, or she was your neighbor, while you probably find her attractive or charming, you would never in a million years guess that she is a provider.

This is probably true for all providers/hobbyists to some extent. However...

QUESTION: Who is an excellent provider who particularly struck you as someone you would never guess is a great provider if you met her outside the hobby?

NOTE: Please don't post stories about providers civilian lives. That is highly inappropriate
