He showed respect by calling before arriving and by wearing the booties in my home. Since it is a new system, it could've been treated as a simple follow up, however, Bryant took his time and included me in descriptions and explanations. Also, his awareness caused him to notice and fix, on the spot, a gas pipe that should've had a gradient or $@!#%. The service was well worth it and a pleasant relief from previous issues with Alaskan. Way to improve!
