as dieseldog999 says do not fall into the must go faster trap, do each drop on its merits, keep a diary of time at each drop, stop for your breaks, (taking a break whilst unloading is only putting money in someone else’s pocket and you not getting a rest) I know some people say it suits me and so be it, but things like that grow into 15 hour days, one hour more and its a normal working day for two people, I am not saying slow down passed what could normally be expected, just work smarter not harder.
