  • Basically, at 7:00 am this morning, your crew had completed the whole job. I was shocked and completely amazed that these men could do all that work that fast with very little interaction from me. You should be very proud and happy that Bill and this crew of men represent PLAAS INC, as they set the benchmark for how a crew should not only work, but communicate as well. Thank you very much for sending us such a responsible crew to complete this work.
