if you were to ask me what is the biggest difference between japan and u.s. america, i would tell you that in japan, you can't have it your way. but in u.s. america you can have it your way.
for example, i often go to bagel shop near my place, and they offer a pretty good salmon bagel. the only problem is that they put these green peas on the salmon. so i asked them, to not put the green peas on my bagel. they just looked at me. obviously they were confused. then they told me that they had to put the green peas on the salmon. then i was confused.
so the only restaurants i have found in japan that let me have it my way are burger king and subway. perhaps there are others, but i doubt it.
