... by the hour so the time to ask for directions to the shoot is not when you're already half an hour late and I call you to ask where you are.  That's the kind of question that you should ask me the night before.  Really, some people!

Oops that sucks.
I don't even leave my place untill I know where I'm going and have my directions printed out,
usaly the night before.

ughhhh

when i first started shooting I asked myself... "will I waste money renting studios and the model be late or not even show, or will I buy things I need and makeup my own studio"......

I went with option 2 

sometimes 'the force' works to find a place, and sometimes it dont

I usually send directions to the studio to the model a few days in advance of the shoot and ask for email confirmation that they have received them.
