You have been here and been someplace where they know Cement.
I had the same shit when I was new here and started a house, but soon learned to call CPAC order what I wanted and made the driver listen to me and not the crew on the ground, I had 0ver 50 years in Construction when I came here and my start in construction was on a D handle scoop shoveling sand and gravel to a hopped mixer on large construction sites.
