Heathen! Subs are a subtype of sandwich. And a burger is a type of meat patty. I never had them with buns as a child. /tragically deprived

Basically every type of sandwich (or sub or roll or *sullen glare* "hamburger") ever served in a commercial establishment barely fits between my jaws. Maybe if that is not your usual experience this is an experience to be strived for?? o_O
