solution, fire Bob and build unboxing robot.
Bob comes to me and says "Hey blackdog, can I get you to fix my water heater? We haven't had hot water all week and my old lady is getting mad?
No Bob, I cannot, but Home depot sells new heating elements and they are easy to replace.
"OK", says Bob.
"Hey blackdog, I did what you said and I still have no hot water"
Really Bob? Tell me what is going on?
Well blackdog, I've put four of those heating elements in and I hear a bang and then nothing comes out of my faucet."
Bob, do you turn the water back on after you replace the heating elements and before you re-energize the breaker?
"Why?, What do that do?" says Bob.
With all the Bob’s and Roberta’s out there, I’ve got a pretty good gig until retirement and then some.
