Miracle Restaurant Raiders

The upstairs guide is from here, and it's more comfortable to see.

1. You are playing Generation 1.

2. I remember whether the fourth level or the first level can be trained. (Or you can train directly by playing free mode).

3. Most of the customer complaints are complaining about bad attitude, rudeness, etc. It's very normal, I don't know how long I struggled with it when I played.

Solution: 1. Wait! The guide says that delaying time is a good way to do it (telling you how to delay time, since most of the tasks are profitable, so you just need to change the discount on the menu a few minutes before you leave work), because the experience points of employees will increase over time.

Training can just play an accelerated role)

2. Hire employees with relatively high salaries (who have a higher initial experience value) and then reduce their wages back to the level of others. (As long as the salary cut is not too severe, it will have no impact on profits) (it can be seen why the boss in life refuses to raise his salary).

It's super detailed here.
