Have gone by many times when they are supposed to be open and the door is locked and no sign posted as to why they are not open. This has happened too many times over too short a time frame to be reasonable. I can understand that they may be pretty busy, but if they do not want walk-in customers, they should at least advertise it so, in order to be honest with the public, if nothing else. Maybe even advertise for walk-ins to call first?
