I could think of a few places where such a request would be frowned upon. But if the OP is putting teriyaki sauce on his sushi, he's probably not looking for an expensive, ultra-traditional sushi experience.
The cheap places are coming up with lots of new ways of preparing sushi to try and attract customers.
