You think that you are really good at handling the money? Here is the way in which you can test your skills. The game is quite interesting and fun. You are the cashier of your own grocery store and you have to keep the record of the sale. The more you play the game gets faster and more complex. You have to be really quick in addition and subtraction and in the money handling because there are going to be customers from everywhere. There are going to be actual market rates and registers available so you are not supposed to play it casually; It is a real cashier job.
