“I know I have mentioned it before, but I wanted to reiterate again feedback from site. All your tanker guys are outstanding. Their work ethic is amazing, and they conduct themselves so well on site and its absolute pleasure to work with them. Only wish is that you had more vehicles and more staff that we could use on every tanker job we have. Please pass this back to the boys and the powers that be up above as they should be aware of how lucky you are.”
