What common design feature do you absolutely hate?

For me, it's public toilets that have those really long continuous sinks with loads of taps but only one soap dispenser right at the end. So if you're using a tap towards the middle, you have to squeeze past five people to your right, get some soap and then return to your tap. Why not just have a few more dispensers further down the sink? They seem to be designed to look nice rather than let everyone wash their hands and then get out. I've been in three different public toilets this week that had this sink design.
