I usually stick between 10 and 15 but went about 10 down a long driveway and was cussed out by the customer. “How about not fucking flying down my driveway. I paid 20k for this” It was my first time delivering to him and I guess my quarrel isn’t how fast you should go but more so how I was approached. Hell I’ll get out and walk your package a quarter mile down your driveway if you ask me like a human being. Spend 20k on shit ton of rocks but can’t shell out 75 bucks for a delivery box.
