Getting paid cash,(check), after a job "101"
#1 :Tell them you can't come out and do the job unless they will fork over a check afterwards.
(true story), Went out to fix an inferior welders work on a workover rig the other day. Told the pusher exactly that. Pusher told me to bring my certs, cert of insurance, and w-9.
Got a 1200.00 check
Yep, it works sometimes......
