I don't open my door until I open, at 7:30 a.m. I tell them this at the main interview, and when they're signing the papers; I also state that I program all my clocks to the Ottawa Weather Network, and for them to do the same. IF you want me to open at 7:20, you have to pay me more ($10)!

Just don't open the door for them. They'll soon enough get the point.
