Customer feedback highlights mixed experiences with service representatives. Reviewer Aaron Masters specifically names Jarod as a technician who communicates well, arrives punctually, and consistently completes work under estimated time. Another reviewer describes a positive grocery store encounter with an employee who proactively assisted a customer searching for products. However, three separate reviews document concerning driving behaviors including texting while driving, excessive speeding, and aggressive maneuvers on public roads. These negative mentions describe specific incidents on Marvin Road in Olympia, Highway 512, and Puyallup area roadways.
