Congrats on your CINC HOA coin, SIERRA HOTEL!
The biggest bar tab I saw was from a poor coin-less 2LT at the airport in Dublin, Ireland who had to buy pints of Guinness for about 200 guys on our way home from a deployment. Lesson learned the hard way! LOL
After 20+ years in (last 12 in Special Ops) I gathered quite a collection. The most special ones of course are those awarded for a job well done. My favorites were from 1st Special Forces Operational Detachment-Delta and SEAL Team-2 in Bosnia, one from Commander-USSOCOM for rescue of F-117 pilot, AC-130 Spectre Gunship Close Air Support missions in Kosovo (jeweler buddy dipped it in gold for me), and another Commander-USSOCOM coin for operations in Iraq.
They are all priceless to me, but this was my first.
