I have a pop once in a while, but depends on what I am doing.
If I am having a pizza, I like a Pepsi.
With burgers and such, I like a 7up.
pop! Damn Yankee!
A woman who I worked with related that, years earlier, she had worked at a business across the street from a motel which had a soda vending machine. One day she asked her boss "is it okay if I go across the street for a pop?"
