What are jobs in the hotel industry (at least 3)? Give some brief information

about them?

1 . Executive chef - The executive chef oversees all the dishes and makes sure they are perfect he/she also cooks food for celebrities and people of a high status

2 . Front desk - Helps people check into the hotel and helps people with anything they need. Also answers calls from rooms and tells staff at hotel what people in the room need

3. Housekeeper - Cleans room while guests are out. They change sheets towels and soaps.

Hope it helps

Now, you can do this in many ways yet a few ideas are
Have a great conflict arise within the characters or in the plot
Add more characters
or even have the setting change in the writing which will allow for more dialogue to continue  
Hope this helped!!
