Gas stations/convenience stores in the hood are usually cash cows. The markups on beer, cigs and junk food are pretty hefty. But, of course, if you work there, you're behind bullet-proof glass all day.
If you look at the locations of Tesla superchargers that tend to be at upper middle class destinations this is because Teslas are intended for that demographic. We have bucees mega gas stations all over Texas and they all have at least a dozen V3/4 Tesla chargers. This is squarely targeting the middle class as bucees tends to be the Wal-Mart of truck stops. The other locations you always see Tesla chargers is outlet malls and any entertainment district with night life , and restaurants. The fee to leave a Tesla in a SC spot past its full point can be $2 per min at peak times so most people move them as soon as it’s done. You can reserve a spot for the same $1_2 a min therefore keeping it open for you even if someone pulls up into it the cord won’t charge it will.show reserved no matter how many times you plug it in and out eventually they get the point and move on. These are non Tesla drivers a Tesla would show that SC as reserved on the dash pad. The screen on the charger itself shows this but you will see people still trying to get around the lock out.
