Gas station coffee, with some exceptions I'm sure, ranges from brown piss water to passable. Starbucks is overpriced and its almost certain there's a local shop just as good or better near you you should go to....but commerical coffee machines are better.

If you're the kind of person who drowns your coffee in milk and sugar then it's kind of a wash (espresso not withstanding), but if you take it black like me you can definitely taste a difference between office kcup pod coffee and actual coffee shop coffee.

Now mind you I'm not so stuck up that I won't drink the cheap stuff but it is a nice treat to get a solid quality cup of coffee when you're out and about.

Edit: if I made six figures and had the time to stop at a coffee shop every morning I could probably see myself being one of those tbh...
