In the episode where Peter, Lee, and Shane discuss watching costs and hidden fees, they likely emphasize the importance of closely monitoring expenses in a pool service business. They might talk about how costs can quickly add up in unexpected ways, such as through hidden fees for parts, equipment, or services, like increased shipping charges, vendor markups, or fuel surcharges. These fees can chip away at profits if not carefully accounted for.

The trio would probably suggest strategies like negotiating better terms with suppliers, being transparent with customers about any necessary surcharges, and conducting regular financial audits to spot where fees are creeping in. They might also cover tips on using technology and software to track and forecast expenses, as well as the value of teaching employees to be mindful of small, recurring costs that can significantly impact the bottom line over time.

Ultimately, the goal would be to empower pool service professionals to take control of their finances by identifying and minimizing hidden fees to preserve profits.
