/**
Refactor this program to make it less repetitive.
Notice there are several drinks, and the code to get the total sales for each is very similar.
Can you create and use another method (or methods) that will be called from the coffeeShop method,
to make this program less repetitive?
Hint: would an array of drink names help?
Hint: create a method that takes the name of a drink as an argument. This method can calculate sales for that drink.
The total lines of code in your program should get smaller. BUT, don't just delete lines,
or compress more than one line together. Your code will be reviewed for clarity, readability, and logic.
