Scary

I am sure the technician working on the 8th floor apartment is not scared. If he were, the AC technician wouldn't be up there without  safety kit , doing what he, presumably, does on a daily basis.

The workman,  presumably,  reckons wearing safety belt (as per work manual) is a nuisense. And I confess, it didn't occur to me then,  to do anything other than photograph his foolhardy. act.     

I could (should) have gone down to the apartment below, and given the chap a piece of my mind. But then it wouldn't have been socially correct.
 (Some 10 minutes after taking the photos I looked down from our bedroom balcony. He wasn't there.)
