A few years ago, under senior management's watchful eye, I had to erect a new bathroom cabinet, one of these horrible flat pack kits from you know where. Anyway, after fighting the user instructions to get it assembled, I measured up, drilled the holes, etc and finally mounted it on the wall. Only when I finally put the glass doors in, and they immediately fell out, did I realise it was upside down! Much mirth from senior management of course, who in her wisdom, decided that she wanted it moved an inch or two anyway. So I unscrew it all, remove it from the wall, measure up again, drill the new holes, and eventually remount it in the new position. Go to put the doors in again and what happens.......?
You've guessed it,............ upside down again! Took a lot of living down.
