One of our "b" units was to deliver to a plant that closed a midnite but the shipper had made arrangements for someone to stay until our truck arrived. The truck was there at 12.30am but the plant was closed and didn't reopen until 5.00am we are charging 4.5 hours detention time at $20.00 per hour. Is this a reasonable rate if not what does your co. charge. our policy has been all delay pay goes to the truck not just the 75% of billed amount. Any replies will help as I want to be fair to the o/o and the shipper.
