I own a coffee shop in addition to my tech work. Most people know having runway is important to any startup. If he had to declare bankruptcy 6 months after opening he wasn't set up for success.

If you make good coffee, choose the right location, and do a decent job of marketing you can get cash flow positive with time. Acquiring customers can be slow, but once they taste good coffee they will come back.

Much of the other comments here are true, you don't open a coffeeshop to get rich. The only way you can make good money is to scale into multiple locations.
