If no customers are in the store, it should take no longer than 15 minutes. Also, the employees are allowed to use any printed materials they may have in a binder to answer the questions. They can even read them off to you right out of the binder. I had one store once where the employee couldn't find the binder, so they called another store and read off the answers given to them as the other employee read the answers to my store employee over the phone. The point is to make sure the employee(s) would know how/where to get the information if and when they ever need it. Easy peasy.
