One hospital I use to transport too has 2 towers built into a side of a hill. When they were connected some genius decided that the 5^th floor in one tower would be the 4^th floor in the opposite tower, even though they were the same level. More than once we came out to the wrong unit because it was built to confuse. These towers were built long before I cared, so we couldn’t complain to the idiot who designed them.
