and you don't accommodate, you're probably a bad businessperson.

I have a cousin who bought a coffee shop and only sold coffee, no pastries, etc. She also didn't open up until 9am(It was on a semi-major highway in rural Wisconsin, with tons of commuter traffic). Two of the most important things about owning a coffee shop are being open when people want to drink coffee, and having food to go along with the coffee. She no longer has a coffee shop because she wouldn't provide what the market demanded.

A business creates and delivers something of value that people want or need at a price they are willing to pay that generates enough profit for it to be valuable enough for the owner to keep it open.
