On my microwave you can keep pressing the "start" button to add 30 seconds, but if you press it too many times in quick succession it ignores some of your presses.

My oven requires you to use button presses to set the desired temperature, but if you press it too many times in quick succession it ignores some of your presses.

My car has button presses to turn heating/aircon/blowers/etc. on/off but if you press 2 of them in quick succession it only registers the first one even though they're plainly separate buttons.

It is very frustrating to find that even physical real-world buttons nowadays are controlled by computers with incredibly poor debounce code, or something, so that real buttons now are just as janky as software buttons.
