 		 #146912 - extinguisher
Responding to: ???'s previous message
The "extinguisher" saying is here thanks to Neil Kurzman. Thanks, Neil!

Just maybe one idea, you might like it or not: you may try to build in an "EMI detector" into your circuit, maybe with a big big red LED which would flash like crazy if a sparky motor or contactor is nearby. You can then throw it onto the customer's head: look how much electrosmog you have here - mind, this might cause you various diseases... :-)

I know this is more psychology than electronics but maybe worth trying...
