As long as you guys don't try to claim you invented the burger, as you do the sandwich, we're all good.

(Spent a few weeks in the UK maybe 10 years ago. Stayed at The Earl of Sandwich's mansion now a hotel.

Tales of his exploits o'sandwich creation abounded.

I wonder how true that is. Bread is from all ages. I'm sure people figured out you could put stuff in between before :)
