food service idea

park a snack truck at highway rest stops that dont have any food service. bring a port a potty too if they don't have one. charge people to use it who don't buy food. have a vending machine for during the night.

problem:

cups are not easy to drink from while laying down.

possible solution: have a cup with two sides one for drinking while sitting up, with a normal lip the other for laying down, with a concave lip that holds back liquid until it has reached a more extreme angle.
