Would you honestly turn away a customer that was on a limited income, IF you knew that they would be hard up for money or would be a poor customer in the future. I mean, lets say that you take on a customer, that has a limited income. You give her a pretty descent price for mowing and you she wants you to mow the lawn every week, and do other stuff for her. But in the back of your head you kind of get that feeling that this customer will turn into a bi-weekly mowing customer, that does not won't spring/fall clean ups done, and the chances of you getting any additional work off from them is slim. She will call up constantly telling you that the lawn does not need to be mowed, when in fact it does. Would you still take on this customer? And what happens when she tells you that she can't afford the lawn to be mowed every week, would you drop her and feel guilty?
