You keep their money. It's always good business to know about new customers before they walk in your door. The justification for profit is profit. New customers are like razor toothed grie-worms. They can be succulent, but sometimes they bite back.
Employees are the rungs on the ladder of success.
Don't hesitate to step on them. Never begin a negotiation on an empty stomach. Always know what you're buying. Beware the man who doesn't make time for oo-mox. Latinum lasts longer than lust.
