First job of the day

a third floor flat in a church housing trust.
Nothing to difficult apart from the distance from van to third floor going through numerous security doors. so to make thing a little simpler I drove around the front of the block were . although a busy road I could park and get nearer to custys kitchen window and work that way.
Carried up a length of 2" hose to lower down to ground floor to `connect next length . Big mistake
I normaly take up a bungee to support hose and stop from falling back, not this time

.custy offered to hold hose whilst i go back down collect what i need . I am just collect more stuff from van when suddenly I see pipe sliding from window at a fast rate of knots , and then smash the cuff swings up and smashes window

fortunatly I wasnt directly below
What happened the custy phone went and decided to answer, saying thought the hose was secure.
So whos fault was it? I say mine , and took responsability.
Custy said his , and dont worry it just an accident, very nice chap
Outcome I cleaned his carpets for nothing, and all parties were happy

I asume my fault for not been vigilant. so what do any of you do to secure hoses in this situation , is there any thing better than a bungee?
your ideas and thoughts apprieciated,
Stupid geoff

Ps another lesson learnt.
