It's funny, I had my last day today too, but actually wanted to leave quietly - we did have a very pleasant squadron lunch a few weeks ago, so I can't really echo the feelings of the 'dog' above. Things have changed though.
I did have a twinge of sadness after 19 yrs today as I handed my ID card over, but was brought sharply back into reality when the PSF Cpl told me that I probably wouldn't get my gratuity until the end of next month (Apr), as 'they' have decided to ditch the interim pay runs, despite an agreement to pay said gratuity 5 - 10 days after one's exit date.
Oh well, this time next year, I'll be a millionaire.
