Funny, I hate American sandwiches. I usually ask for half meat and then throw some more of the meat out. If I wanted to eat just a stack of sliced ham that’s what I’d do!
As someone who's grown up with Swiss bread, this is exactly the bane of my existence with most food outside continental Europe. Can't live with plain tasting bread. Luckily Japan is slowly getting the hang of it, so I'm saved for now.
