not saying it is the case but a lot of restaurants I worked were cash only because their supply chain was very low tech (also cash-only) and they simply didn't pay the taxes.

Gas stations might be higher at least in the USA because the kick back for gas is sometimes higher (e.g.: 1% cash back). Also, gas stations seem to really don't want to handle cash those days.
