This is how a game should be, simple and fun!
Very fun game, challenging in some parts but the end result is that it is a great thing to work at a gas station (on NG of course) XD.
Anyway great art, flash, everything was amazing about this game. Although, you should include a property thing where you can upgrade your locations and such.
I think that trying to manage all the different customers is a lot of fun. The game has a good match between the art and the music. I don't know why you have to enter a name to start the game, it doesn't seem to do anything in the game.
I like simulations :) Good! Well done
