Why Are GR’s Admiral Gas Stations Showing Up on GrubHub?

I came across something today that has me a bit baffled.

A friend of mine posted a screenshot from GrubHub of a place called "Admiral" on 28th St. that featured a super swanky menu. The weird thing? It's an Admiral gas station near the corner of 28th and Division.

Now, I know that you can get some food at said gas station, but I don't know that it's the menu listed on GrubHub - it's more along the lines of the 99-cent fountain drinks that are advertised in this sign pictured on Google Street View.

So, I decided to see if maybe it was just a glitch with her app, or if this happens to everyone. I searched for "Admiral" using GrubHub on my phone, and got a similar result - though not quite the same.

The Admiral (with the same menu) that popped up for me was said to be located at 2366 Alpine Ave. NW. So, I looked up the address in Google. It is ALSO an Admiral gas station (Marathon Admiral gas station to be precise.)

NOTE: They were offering up that same 99-cent fountain drink special when Google rolled through.

Why is this happening? Honestly, it's unclear. I tried searching for Admiral on GrubHub's website and didn't get any results, BUT - when I searched for a specific item on the menu "boudin", the Alpine Admiral location was the only one to show up.

Also? As I was typing all of this out, GrubHub asked me if I still wanted some food from there and informed me that "there's something delicious waiting" for me...

Are these Admiral locations doing some sort of "ghost kitchen" concept to make some extra money during the pandemic? Is GrubHub pranking us? Is someone pranking GrubHub? I contacted Admiral and they didn't seem to know what I was talking about (or seem that interested in talking to me. I think they were busy.)

If I find any answers, I will definitely let you know.
