Had one last week who pulled up and started giving me $hit about all sorts ... revenge today.. he turned up on a different job site and it took 45minutes to pump his load with the truck on tick over and the remote on no. 1 -all into a nice big oversite that should have taken 5 mins. Not a peep out of him but he spun the wheels off the site for about 100ft  up the road!!!!!

the old grease on the handle of mixer driver door handle always works, or you could just dumo the rest of his water tank in his drum thats always nice

KA-BOOM KA-BOOM!!!! Oh Whoops my bad!!!!

I usually ask how many days have you been driving a mixer.That usually get the blood pressure up.Besides that if they work an even keel I play nice,if not I know how to make them miserable.

hey murf ! nice work

If they give me a headache for nothing i wait till i have finished then just keep pumping , i totaly ignore them, let the hopper go just on empty them rev it up and suck back ..... heheh have a nice day!
