You think the plumber doesn't mind removing your clothes from the closet to access the crawl space underneath.

You think your plumber is a baby sitter and loves to entertain your children.

You wait till the plumber puts all of his tools away before you tell him there is something else you would like to have done.

You ask questions while he is under a sink or working on something instead of waiting till he is finished.

You try to renegotiate the price after all the work is done. 

You say you only pushed the red button on your boiler once, when you know you pushed it many times.

You don't think it's important to tell the plumber you used a chemical drain cleaner before you called about your clogged drain.

You think a 40 watt light bulb is all you need in your boiler room.

you continue to use the clogged water closet for several hours before the plumber can get to your home

Please keep in mind Plumbers don't like the gruff image that has been bestowed upon them, 
And would like to be given the same respect that they give. 

We are hard working, Intelligent people, providing a valuable service.
