Just realized half the guys on site don't know how to read a slump cone right

I was on a driveway pour last Tuesday in Phoenix and watched three different finishers grab a sample from the same truck. One said 4 inches, another said 5, and the third called it 3.5. How hard is it to set the cone on level ground, lift it straight up, and actually measure from the high point? Are people skipping the basics now or am I just getting old and grumpy about it? Any others notice this slipping lately?

Last Tuesday I watched a kid on our crew set a slump cone on a slope and then try to measure it while holding his phone in the other hand. Called it 5 inches but the whole thing tipped sideways and dumped out before he even got the tape out. Then he argued with the pump operator about it for ten minutes. I swear half these guys would mess up a yardstick if you gave them one.

Give the kid a break, we all learn by messing up first.

Right there with you @fisher.jessica. Had a guy on my crew once try to level a screed by eyeballing it from fifteen feet away while his buddy was pouring the concrete. Took us twenty minutes to fix the low spot he left and he still swore it was the mix's fault.
