Taps that turn the wrong way, and usually both then turn in opposite directions. I nearly broke one in a guest house as I assumed it was just a bit tight!
It is doubly annoying for me from the time I used to SCUBS dive and one of the important "skills" is turning valves on and off behind your head so the "muscle-memory" is quite ingrained.
I used to live next door to someone who worked as an engineer for the local counsel - basically designing the roads and how to fix/upgrade them
Apparently at one point they were discussing the emergency equipment bins they have scattered around the main roads with "things needed in emergencies that counsel staff need access to
Not surprisingly bits keep going missing - adn they were discussing what sort of locks they should have and how to make sure the right people - which went from people like him to basic road workers - could be issued with the keys
Clearly there was a problem because keys get lost if they are not used often
Anyway - the solution they came up with was a simple screw head on a bolt holding the lid closed - normal slotted screw head as pretty much everyone has access to a flat headed screwdriver
but left handed
they tried it and it worked
main problem was that some of the bins were found to have very tight locks that needed some force to undo
theory was that these were ones were people had tried to take stuff - and just tightened the lock instead
The losses from the bins basically stopped
just because people are so used to how to undo a bolt/screw normally they never try the other way
