Kitchen coincidence

We visited some friends who just bought a bakery in a city just north of us. We don't visit them often but had a morning to check out the place. When we got the tour of the bakery, they mentioned a woman who rents the kitchen to make baked goods of her own on the side that she sells at farmers' markets. About a week later, a co-worker next to me had her sister visit with her kids at work (we work in a city probably 15 miles south of the bakery). After her sister had left, she shared some cookies she had made. I asked if she made them for fun or as a business, and she said she makes them as a business. I mentioned my friends who have a woman come in to rent space from them to also do this. I kept asking more questions and we came to the conclusion that it was the same person! That woman who rents is my co-worker's sister. I find this so unlikely that her sister happened to come in to visit and that we happened to go visit the bakery, and she happens to be the same person who leases that kitchen space.
