We prepared a list of question, you most probably need to honestly ask yourself before diving head-first into this wonderful business.
1) Do i know a thing about customer service? Can i handle handling the customers if the need occurs?
Obviously, you don't need to be at the world-champion level at customer service to successfully operate escape room business. But a serious chunk of escape room experience comes before and after the actual game. How comfortable is your lobby? How swift and helpful is your staff? How much time are they willing to spend on each group before and after the game?
Every time i see a bad review for any escape room online - there is (to a certain degree) a customer service failure. People can truly like the game or, at least, be ok with it, but if they had to wait for a long time, nobody was paying attention to them etc - this derails the whole experience.
If you are lucky and good at hiring people - your staff will take care of business. But if you are going to handle gamemaster duties yourself or supervise the staff - you will still need to deal with unhappy people from time to time. Better come prepared.
