Buttons vs Computers

I made a poor bartering decision today. I needed two buttons sewn on my coat. The seamstress needed her computer looked at. The total time it took her to sew my buttons on was laughable, I'm going to guess high and say it took 5 minutes. I got back to my place around 2 PM and I'm just now taking a break at 7:35. I definitely need to work my bartering skills.
