I maintained a POS for a retail chain for a few years.
Our suspend/resume sale feature assumed that a suspended sale could only be resumed on the machine that suspended it. Then we had to change it to be resumable on any machine in the store. But only show a flashing notification that there’s a suspended sale, on the original machine.
(Thanks for storing that knowledge for me for the last decade, neurons. I doubt you’ll be asked to recall it again.)

- LeonB 3y agoReal answer: that’s what the client wanted. > why bother showing the light at all? Probably so that the operator can more easily find the suspended sale in order to resume it. Suspend / resume happens rarely enough that operators aren’t fluent with that feature. > why only the light on the original machine? Because it’s far more likely that the original machine is the one on which it will be resumed, say 500 times more likely. So that’s 99.8 of the time you’re not alerting a second machine unnecessarily - and if there’s three or four machines it goes into more nines of false alerts being avoided. But the sufficient answer is - the customer wanted that. Everyone in the retail chain had experience as an operator (self included) so the user experience decisions were generally well grounded.
