Delivery Guys

Can someone tell me if you are a delivery guy do you have a set amount of time you wait for the customer to reach the front door? Something like .005 seconds? We just had something re-delivered (so Mr. Delivery Guy we really do want this item) do you think you could wait longer than the nano second you usually do? Our house is very long...it used to be cow sheds in the 1700's and they had a lot of cows! It takes us about 30 seconds to get to the front door. Is that too long to wait for someone? Come on guys give us a break here. This morning I almost ran to the front door and by the time I got there Mr Delivery Guy was on his way back to his van. Due to this virus I was wheezing like a stream train by the time I made it to the door! We all know you need to get to the next drop off but how many times do you want to re-deliver to the same address because you didn't wait long enough? I need a nap now!
