I generally don't call before 8 w/o prior permission
Sometimes that's un-avoidable so then I'll do 7:30
I have woken up people, but not when I thought
Ya know like 10:30, or 2:30
One regular customer I know not to call before noon
I figured it out, but he did make it a point to tell me straight out (at one point) "You know not to call me before noon"
I have a separate business line in my home, and although I will answer it at night, I won't during dinner (well, generally...I do have the C.I.D. and sometimes I can't let the call slip by...)
