Imagine going to a shop to buy a drink, and you ask the storekeeper "what if I bought this can of coke?" The storekeeper would have to figure out if he should say "then you have to pay me $1" or if he should say "then you would be missing out on this beer" (i.e., he has to figure out whether you are really asking how much it costs, or if you are asking his opinion on what drink to buy).
