Keep your customers happy – Aside from simply serving them in a timely manner, you can buy treats from the store as well as upgrades to your restaurants, which all will keep customer’s hearts up. The happier a customer is when they leave, the more tip money you’ll receive.

Click on presents quickly – Occasionally while playing, a present or sack of coins will appear on the screen. Grab them quickly to get their bonuses before they disappear.

Serve in order of patience – Some types of customers are more impatient than others. Try to serve the more impatient customers first, as they’ll often tip more if served rather quickly.

These are just a few hints to help you out. If you have any other suggestions, post them below!
