extension cords, one badly patched with peeling brown packet tape and routed them straight across the sopping wet tile floor where everybody has to pass...
Now this says to me "YIKES". People forget with regard to water, human skin resistance drops to incredibly low levels when wet.
Although an RCD/GFCI will cut off the current quickly when its trip rating is exceeded, in the time before it trips [generally quoted as 40ms I believe?] that is 2 complete cycles at 50Hz, the
current will reach a much higher level than with dry skin. That kind of thing doesn't just scare me, it terrifies me. Like most people on this forum, I have seen what electricity can do at its worst. Most people have had 'a jolt or two' and it 'wasn't so bad' so they don't see what the fuss is all about
.
They may have got those 'jolts' under less than ideal circumstances from the current's point of view, and the next time won't be so lucky if water is involved.
