Ok, this is something, as a courier, that my char's have been dealing with for awhile now.
I understand that there's only so much stock to be run in a day, but if i do some runs at 9am, then come back the next day at 830, Larri tells me "Bah, stop harassing me, come tomorrow or something."
that's a 30 minute window.
now, i understand some may say that abuse can happen if it was too short, like "Roll it at midnight", but not really. Because if i finish my runs at 2350, and then do more at 0003, i'm still only getting the runs that i would have at any time during those two days.
*actual idea*: a roll for the couriers at midnight instead of 24 hours from last job i think is a good idea.
