I prefer the pickups that agree to a flag system. If you don't want me to stop for your daily pickup put a sign out. That way we still get credit for swinging by.
If the sign says "no" do you still stop and complete the pickup at that location or do you wait until you get to your next pickup stop? If you wait you are actually falsifying records.
When I was a new driver I got burned by a pickup stop which put the sign out after I had already driven by their location. To this day I refuse to allow pickup customers to use the sign system. They pay up to $20/week to see my smiling face.
Our center "encourages" our rural drivers to call their pickups, especially if they are running late. While I understand the rationale I totally disagree with this.
If your flag pickups ship on an infrequent basis you might want to suggest they convert to a Smart Pickup.
