Being a bartender is not an easy job. Every customer has their favorite drinks and dishes. And you have to satisfy all their requests as quickly as possible.
The sooner the customer gets his order, the more points you get.
With each level, the variety of customer requests and their number grows.
If it gets really hard, you can take a short break.
Unfortunately, as soon as you break three dishes, you will leave this establishment and start your career all over again.
