Boltondave: Why do shops use a computerised till, when they know (and admit) that it's not working properly?
I have never known an electronic cash register to calculate incorrectly. Or an electonic calculator for that matter, unless there was a power failure whilst calculating.
I hear that magnets are pretty good at screwing over some calculators.
Well apparently one would be able to screw up the ability of my graphical calculator, but its also apparently possible to fix it using the magical "reset button" that you need an incredibly long thin object to reach.
