What in the world are you talking about?They'd "bother" if it became a state reg, anytime a hurricane evac order was put in place.
Transaction limits at gas stations are "x" gallons per fill.
If you run multiple cards, you are recorded on camera (all stations have cameras), and they send that recording to the state; they get 90% of the $100 fine and would be financially motivated to do so. Just "10 cheaters" nets them $900. Make that income 'tax free', and they'll hire extra attendants to monitor for that profit whirlwind...
Now I know you have never been to Florida. 😂
