My solution to retirement party was announcing that I'll not be present for the party.
When the party idea was initially presented, my point was that I arrived as a nobody, just another cog of the many in the big wheel. That big wheel keeps on turning just fine without my presence.
Instead, I suggested that they have a good riddance celebration. Heck it opened up a promotional slot. It worked. I think, since I was not present, nor have I ever gone back or contacted anyone at the w*rk place.
I read in the papers that the trains were as usual mostly on time, no more than the usual number of breakdowns. The passengers never give even a passing thought to the maintanece crew, of any of the three shift's humans, running 24/7/365.
