Guest become angry when they have to wait for a service. You will see a customer furiously going back to his room. There will be a call out above him with an exclamation mark. This usually happens when the customer waits in a line to eat food at the restaurant and does not get a seat.
Make sure you have enough tables placed on the restaurant. If there are only two tables and six guests, then only four guests will be seated whereas two will have to wait out. This is when they irritated and go back to their room. Angry guests in Hotel Empire Tycoon check-out very soon.
Along with the restaurant, you should also pay attention to the bar. Have enough tables so that the bar can accommodate several guests at a time.
You should also hire bartenders and chefs. Two bartenders can attend 4 guests at once. The same goes for chefs. They will also attend four guests at once.
If there are 6 guests at the restaurant, then chefs can only attend 4 at a time. The other two will have to stand in a queue and wait for some time until one of the guests leave the restaurant. If a customer standing in a queue loses patience, then he will leave the restaurant, go back to his room, pace restlessly around his room and finally check out.
Make sure rooms are not dirty. As you build more rooms in Hotel Empire Tycoon, you will have to keep them spick and span by hiring an extra housekeeper. Normally, two housekeepers are more than enough for 5 rooms.
If you have more rooms you will not only need more housekeepers, but also have to upgrade key items, such as Cleaning Products and the vacuum cleaner. Both reduce cleaning time, ensuring housekeepers clean all rooms faster.
Guests are patient enough, but if they see the room is dirty for long, they might be angry and check out. Sometimes, the game will post an offer to clean all rooms at once if you watch a video. You can use this offer to clean all rooms instantly if the housekeepers can’t clean all rooms.
