ELI5: In an area of gas for $2.09+, why doesn't/can't one gas station just destroy the competition by selling gas for $1.99 and advertising it heavily?

Many gas stations sell gasoline at a tiny profit margin already. I've spoken to a gas station owner who makes more money on a single cup of coffee than 8 gallons of gas. This is also why they are allowed to charge different prices for credit card purchases versus cash. The small fees that credit card processor charges them is enough to totally eat up their profits.
