What's to discuss?

Are you of the view that all the coffee on offer is of the same grade and quality?

AFAIK, 'gourmet' is not a legislated, protected or standardised term, anyone can use it to promote their blend or brand. One would hope that it is mostly used to describe a higher quality (and better prepared/fresher) coffee/coffe blend, but there is no guarantee this is the case. What is nearly guaranteed is that consumers are often willing to spend more on coffee convincingly marketed as 'gourmet'.

So I would surmise that either

The 'gourmet coffee' you have tried isn't of a higher standard than the coffee served to you at gas stations.

or

You are perfectly happy with 'ordinary' grade coffee and dislike the higher quality stuff.

This second conclusion is nothing to be ashamed of. Chocolate is an excellent example of another bean the majority of Western consumers prefer, if they're being honest, lower quality versions of. A huge proportion of self-confessed 'chocolate lovers' or 'chocolate addicts' would much rather eat the chocolate and milk flavoured fat peddled by Hershey and Cadbury to real, plain chocolate with a high percentage of Criollo cocoa beans. You wouldn't be alone in preferring a cup of coffee from a gas station to a cup made of freshly ground beans from Jamaica's Blue Mountains.
