Done Don't get the reference

[magnetdance]

Hi guys,

I'm stuck on this one highlighted bit. I think he's referencing something but since I don't know what it is I have no idea how to translate it.

Help?

I don't think he's referencing anything, it's just a very formal manner of speech. "In the event you go independent (I guess he means open your own restaurant?), I will become a regular customer."
