People don't show up on time because there is not money waiting for them, you ever pass banreservas on payday? Ever had a gardener whos payday was a Tuesday and find him loitering around the gates on a Monday. Order from a calmado and have the delivery within 2mins, no change, that's ok he takes your cash and returns with the change later that night after you made several calls to ask what happened. Electricians start a job, take forever, but once complete they'll be knocking on your door at 8am. monkeys and peanuts! Primitive mentality, it's only Important when they directly benefit immediately. I train my dogs like this!
