Getting more money from cafe's world

There is a way to get more money if you have the time to ask you friends/or create new facebook accounts to send you gift. There's a bug where you are allowed to send to the same friend everyday. So, send the gift giving the most income to your friends 20 times (This is the limit that facebook allow you to send, if you send 1 to another friend, then you can only send 19 to the specific one). Afterthat, go into your account, accept the gifts and run your cafe's world application. If you notice that everytime you log into your cafe's world, there will be quite a number of customers. Wait for around 10-20 second so more customers will come in, then use your gift. (This is not really required, but will allow you to get the most money.) You will see the tips from your customers at the top of their head. To use it consecutively, wait for the image on the top of thier head to disappear before using you gift, otherwise, you will waste a gift.
