There are a few everyday designs which absolutely infuriate me because they are poo poo. The classic example is the rod-operated bathroom sink plug mechanism:



It's a good idea in theory, but the loving things have a real propensity to malfunction. If a design cannot operate for any length of time without a good chance of it malfunctioning, then it's a bad design. How many hotels have you stayed at with these stupid plugs which don't work properly?

What I don't understand is why they are still so common when they break or stop working so easily and frequently. What other bad designs persist despite being rubbish? What gets your design goat?
