Crush on a receptionist?

I live in student hostel and I have a crush on a cute receptionist that works there. she is very sweet and friendly person. I know that its part of her job to be friendly. so how to tell if a receptionist is interested? i wanna invite her to a dinner to get to know her better but i am hesitant because I dont want to cause her trouble with management.
