I've just let my first customer this year know that I'm adding a fuel surcharge every time I mow and trim. He grumbled a bit and said the gas prices are not much higher. I reminded him that when I began mowing in April, the prices were 20-30 cents less. Has anyone else added a fuel surcharge this year? How do you delicately inform the customers their fees are going up without offending them? And yes, I did retain the customer.
