We have a coffee machine at work which produces cheap and nasty coffee, which at least isn't expensive and nasty, but compares badly with the cafe which does cheap and nice coffee but closes at 4 pm.

The machine has a light sensor to see if you've put a mug in it, but I can't actually put my mug in in a position that trips the sensor. There's an obvious failure mode in that I forget to put my hand over the sensor and a paper cup drops down.

A less obvious mode is that I put my hand over the sensor but don't put my mug in. :-(
