Subway is fantastic. You should try the Pizza Sub next time you go in, Viper. It's not on the menu, I don't know why, but it is a superb example of all things sandwich! [Drool] Mmmmm..... Pizza Sub. [/Drool]
As for the bread cutting deal: You can ask for whichever cut you want. The "classic" cut, also known as the "U-Gouge," is the one where they cut a trench in the bread. The other cut, the "Hinge Cut," is the one where they just cut straight through the bread, leaving a hinge. I find the U-Gouge preferable since it does a better job of containing an unholy amount of toppings. But, to each his own, you just have to ask for what you want!
NOTE: I don't work at Subway, I just go there all the time!
