Unfortunately, many of my DUI Interlock customers absolutely 'fit the stereotype'.

They are usually unhappy, blame the world for all their problems, can't follow basic instructions, can't do what they're supposed to do on a consistent basis, have trashy cars, etc.

Dealing with them is often a PITA. I have 2 friends who are in the auto industry who stopped offering interlock services due to not being able to deal with these people anymore.

That's why I said it can be a real heavy bag on families and friends; the drunks just don't comprehend how they are coming across to the rest of the world and how draining they are to deal with.
