A few years ago some Greek legislator thought it would be a good safety issue if all showers in hotels had an emergency switch that someone could pull to notify the front desk that they had fallen and couldn’t get up. So every shower had this switch installed but with varying lengths of string on the switch. The problem was that if you fell how could you pull the string to operate the switch. This law was eventually changed, but all hotel renovations in the last 10 – 20 years have this in every shower and the switches are still there. My first time in one of these showers I kept pulling the string hoping it would turn on the overhead fan. It didn’t. I guess I was only annoying the manager on the first floor.
