Up late in the kitchen one night, I noticed the clock on the oven change through the following times:
Hmmm. The hour changing 3 times in 3 minutes? I've never seen that on any other clock. While technically you could argue that it's correct, but it just seems wrong.
If you aren't paying attention to small details which I can see. Why should I trust that you are paying attention to the important things which I can't see.
If you press the volume up and volume down button on the radio in my car when a CD is playing it pauses and the display says 'PAUSE'. If you do the same when the radio is playing the radio is muted, but the display still says 'PAUSE', not 'MUTE'.
It's a small thing, but it bugs me every time I see it. Not a good way to build customer satisfaction. All because, hopefully, something was deemed to unimportant to spend enough time on.
