Re: 5.30 Friday is worse
One place I worked I was told of the Marketing droid who was in the habit of calling product meetings at 4.55. Which then went on ... and on ....
Engineering decided some action was needed.
When all were gathered for the next event and he was just about to start someone piped up to the effect "Oh dear - 5 o/c - sorry - I've got >insert fatuous excuse< tonight - got to dash. This was followed by a series of equally sincere but obviously made up excuses and serial exits.
Said droid was left staring at an empty conference room. I gather he was somewhat unamused but he never tried to pull that gag again.
