Person 1-"Man, I paid $50 for 3 gallons of gas, a pack of gum, and a soda last night at this gas station in bumfuck Egypt"

Extortion, extracting value from legitimate business transactions/operations while providing little to no value, simply because you can. Doesn't come from modern highways, comes from 'highwaymen' who would threaten travellers and merchants on 'highways' (any kind of road up until the 19th century) and demand payment for use of the road, even though it was not theirs to demand a toll on.
These mafia-type guys came to my store and demanded payment for 'protection', it's highway robbery.
