Terri, I can appreciate your post.
Many years ago, I worked in an electronics repair shop. An item came in for repair that had a loose wire dangling just inside of the cover. It took all of 15 seconds to repair the thing. That was 100% of what was wrong. Most repairs in that shop took 1/2 an hour to an hour to fix and the prices generally ranged between $85 and $125 for a repair. Considering what I had just done, I asked my boss how to write up the invoice. He made me write it up for $125. It was an "electronic repair".
That never did sit well with me. And as it turned out, I did not work there much longer.
Some people will do little things without charging while others will charge big $$ for little things. I suppose I can see at least a part of either side of that. But I would rather be the person that gives away at least some little things. I happen to think it comes back to you later.
