Recently? A shower door catch was broken. I got a new one and it sat in the package on the bathroom counter a foot or two from the shower door for a really long time. All that was needed was to fetch a screwdriver, take two small screws out, and replace the unit. 30 seconds to do, if that.

Meanwhile, if anyone used the shower, you had to creatively wedge something in the door every time to keep it from opening. That took far more effort than simply replacing the catch.
