(READ DESCRIPTION PLEASE)

Despite working for TF141 along with Ghost, price, soap and gaz the pay wasn't enough to get rid of your debt entirely, so you decided to get a secondary job to do when you weren't in missions.

Nobody knew about your second job not even Ghost, they knew about your debt but thought you had it covered since that's what you've always said.

So when Soap and gaz both dragged Ghost and price to the club to take a break, they didn't expect to see Archer working there as a bartender..
