A lot of it depends on the driver, especially if you are in the sticks. Some will stay out as late as it takes to get the days run made, others will quit whenever they feel like it.
It also depends what classification your address has. One of mine was classed as "Remote" so they only had to make it there once a week! (Mind you this was on a secondary road about 1/4 mile off of the blacktop and then only 1 mile to the highway.)
All in all I haye UPS with a passion, they have screwed up about 65% of my packages over the last 10 yrs and don't really give a rats behind about it.. (And yes they have reimbursed me for most of it, but not for my lost time or aggravation)
