The map of "pop," "soda," and "coke"

"When on a hot summer’s day you buy a carbonated beverage to quench your thirst, how do you order it? Do you ask for a soda, a pop or something else?

Other generic terms for soft drinks outside the US include ‘pop’ (Canada), ‘mineral’ (Ireland), ‘soft drink’ (New Zealand and Australia). The term ‘soft drink’, finally, arose to contrast said beverages with hard (i.e. alcoholic) drinks.
