Nope, i do the same. I dont call my dealer on saturdays and sundays untill after 1pm too, so he can get up in his own time, eat with his family, bag up my weed ready - but normally instead of calling him i just drive round and knock on the door after 1.

When he was small time and had a proper job too i used to give it an hour after he'd finsihed before i went to pick up so he could eat dinner.
