Love when then concrete sales man says the pump is messed up. 

IT'S ALWAYS THE PUMPS FAULT! Are you new...lol

If we all had $1.00 for everytime we heard this, there would be a lot of rich pump guys out there.

Other company i worked for Had a Ready Mix Company deliberately send an unpumpable mix over, and then bring their own telebelt over to start the job. Mix changed, so my company sent another pump over to show that they were being sneaky. Needless to say contractor changed RM companies after that point.

That shit looks like it came out of an old river bed ive never seen concrete with that kind of stone and that looks so shitty im sure the mixer driver seen that at the plant and probably said something but they said to go anyways unbelievable and of course its always the machines fault.
