Congratulations!!!
On the construction sites we make the old timers sit on a bucket on the last day. That's right, nothing but sit on a 5 gallon bucket. Can't get hurt sitting on a bucket. Usually after about 15 minutes of that, they spend the rest of the morning walking around saying good bye. By lunch time the gang boxes are locked and all the guy's are gone to the local watering hole.
I hope your last day was a safe and fun day!!
