Oh, yes, the old "we don't want to lose customers, so tell them we can do anything they want," ploy.
I worked at a frame warehouse. We sold matboard, mat cutters, foamcore, glass, frames, frame hardware, and glue.
One customer was duplicitous, nearly bankrupt, and would avoid our driver like the plague if the driver wanted to pick up a check. They ended up several tens of thousands of dollars in debt to us.
But when they called up to order the order ALWAYS got filled. Why?
"Because they're one of our BEST customers!!! Their order always tops a thousand dollars!"
Um, no, they are stealing from you, and you are letting them...
They eventually did go under, and left the frame company with the debt.
