That's a perfect example for what we are talking about. You are seeing this from the wrong end.
Suppose a new company or a struggling one which has world class coffee but is struggling to compete with Starbucks or Coffee Day or similar.... Imagine if they strategically bought CoffeeShop.com, created a kickass brand, website and app and gave great memorable service at their newly branded shiny outlets... don't you think with the perfect strategy they can get a big pie off starbucks and their likes??? That's not to even mention the millions who will enter "coffee shop" in search engines
Marketing would be a walk in the park...
Coffee Shop? CoffeeShop hehe. Brands just grow on people (facebook for example). What seems weird now becomes a part of you with popularity. We are talking about getting an edge when you startup or rebrand.
I haven't looked it up but I am pretty sure one of the giants must be owning this domain name and the likes of Coffee.com. Its called taking out the competition even before its born!
best,
