check his work before pay him
We have used Greg Wiska a few times in the past, and due to his good work, we used him again. Without checking his work, we paid him, and found out not only he did not do his work as he should but also he left the door unlocked and left all the lights inside of the house all weekend long. As we shared it with him, he showed up with aggressive attitude almost to hit my husband, so we let him just leave.
According to other cleaning crew we hired, Greg did not do barely anything but he was glad to get our $90.
