What's one thing you wish every customer knew before renting a porta potty?
I run a rental operation in North Texas, and I spend half my phone calls explaining the same things. The one thing I wish every first-time customer knew is that a standard portable toilet is not a magical self-cleaning box. It's a holding tank that needs weekly pumping by a vacuum truck. Your guys will fill it faster than you think, especially if there's a lunch trailer on site. And that truck needs clear truck access, no parked skid steers, no mud pits, no locked gates. If I can't get to it, you get billed for a missed service and your crew gets an unpleasant surprise on Monday morning. What's the one misconception you have to correct most often? Or what do you tell new customers to prevent headaches?
