Design Flaw of the interim:
The post office that I go to on my lunch break has now instituted the rule that it can't give out more than $5.00 in change. I guess they got sick of people complaining about getting a fistful of Sacajaweas. So when I went in at lunch today, I found myself in a quandary. I didn't mind getting two booklets of stamps, but because I had only $20s and singles, I couldn't actually work the machine. Even though I was only going to require $4.40 in change, because it was broken up by the programming into two transactions, I couldn't get it to let me have my stamps.

I don't know if I'm more sensitive to these programming glitches because I spend my work day trying to prevent them, or if I'm just becoming less sensitive to it as time goes on.
