Where did you mention cola in the question?
A sub is a Roll or Sandwich here, Sneakers are Trainers or Runners, and Sodas are called Soft Drinks or Minerals or Fizzy Drinks.
Whats this soda stuff??
It's pop... everybody knows its POP. I pick up my pop with my shopping cart.
Wearing my Tennis shoes because theyre comfy through the store and they have nifty little air pockets in them.
Unless...I step on a nail, then they fart and squeak.
And that's just annoying going in at lunchtime for a Sub.
