You're thinking about starting your own chain of upscale, drive-through espresso stands

You're thinking about starting your own chain of upscale, drive-through espresso stands. You have several ideal sites in mind, and you've analyzed the industry and all the important statistics. You have financial backing, and you really understand the coffee market. In fact, you've become a regular at a competitor's operation for over a month. The owner thinks you're his best customer. He even wants to name a sandwich creation after you. But you're not there because you love the espresso. No, you're actually spying. Youre learning everything you can about the competition so you can outsmart them. Is this behavior ethical? Explain your answer.
