Ok it takes a few tries at most stores to get to a manager who will answer
you, unless the store has just one manager. Don’t take it personally
The managers have a store to run, and honestly you are asking to set up a competing
business in front of them. Keep this in mind while talking to the manager
You may simply have to go to the store and hope the manager you need is there
and available
I prefer to ask for an appointment first, it reflects that you place value
on the managers time. You may want to put a request for an appointment in your
letter.
