I think this discussion of the 2 check makers is very beneficial to the 2 businesses. It gives both Pat and Charles a chance to see what has bothered some of their customers so they can improve their products if need be.
I know that if you sell enough of your product you will sooner or later get someone mad at you.
Pat has been here for many years and has been very open about things that slowed delivery, caused changes etc.
I have also used the tool from Charles. I believe Charles has been here a time or two but is not a regular here. Not faulting him either just a statement.
Constructive criticism helps everyone but grinding an axe benefits no one and most here are smart enough to pick up on those folks.
