Being that you men constantly talk about how you operate your sucessful businesses in comparison to an unethical business practice, let's draw another.
You're out of the office doing your job, because you're good at it and you want to provide the best service without interruptions. You want clients to have a face to face interaction with you, especially if you're in a sales-driven environment. It doesn't matter what the product is. This eats a lot of your time that could be spent answering emails or screening calls. Though that stuff also consumes a significant portion of your day, it also means acquiring new clients, which means more money. In your businesses I'm sure there are people who shop around or general time-wasters with no intention of purchasing your product, so you hire someone to deal with all of these people-- real customers and time-wasters alike.
It's no different. Pussy is product too!
