Almost 30 years ago, I was between jobs after my son was born. We lived in a very small town and the LQS needed help during inventory so I was hired for a couple months.
I remember at least twice having to write them a check for my greatly discounted materials.
I had a great stash already but added to it tremendously. My hubby said I had to quit and get a "real job" that paid us instead of us paying them.
