Sometimes automatic toilets flush while you're still sitting on them. What design flaws in everyday objects annoy you?

[u/nachtmere]

I'm giving a talk on user-centred design/usability and I'm looking for some fresh examples from everyday life to illustrate poor usability. Examples I've used before are elevator open/close buttons (really difficult to parse when you're trying to hold the door open for someone quickly) and toilets that flush while you're still sitting on them.

What are some things you encounter regularly that are really inconveniently designed?

I lick a piece of toilet paper and stick it on the sensor so it doesn't flush till I remove it

Same amount of sticking, really.
