What is one of the worst inventions that you use daily?

This has been inspired by another question posted earlier today, it got me wondering;
What is one of the worst inventions that we use on a daily basis, that is just rubbish?

My example would be the car. It’s a terrifying idea to start off with.
I know! I’ll drive a large chunk of metal very fast towards some other chunks of metal that are also going very fast!
And worst of all, it’s under my control? It’s ludicrous! ... in my opinion.

Anyway, I’m sure your ideas will be better than mine :-)
