making me pay more

No, you're choosing to pay more. Make your own coffee at home. Or hell, don't drink coffee. Nobody's making you do that, either.

A slightly better example might be convenience stores in low-income areas where many people don't have access to transportation to the more affordable grocery stores. The fact that you immediately jumped to Starbucks (something many people consider a treat of sorts) as something you're forced to buy out of convenience shows how privileged you are to have this "problem".
