There are a lot of Shell gas stations that have great little coffee/food take-out stores. Those pay very little, if at all, but you are reimbursed for some fuel, coffee and a pretty good sandwich that they prepared just for you. There are a ton of them in the DC/Baltimore/ NVA corridor, I know, Not my type of shop, but the coffee is quite good!
