Men’s Night Out

The three held back their laughter, forcing themselves to remember his stern image so they didn't break into cackles.

Gill, who was talked to beforehand by Althea, twitched his lips. Instead of answering the question, he filled up his cup. "Come on, Captain. Sister-in-law wanted you to have fun! Let loose for once will ya?" 

Eagle looked at the captain in awe. "Never would I think I'd get to drink with the Captain in a legit pub."

They did drink a bit during those lull times in their missions, but that was when they were camping. And even when they did drink, they couldn't drink too much either because, after all, they were on the job. 

On the other hand, when they were not on missions, the captain was either strategizing, making reports, or simply spending time with his wife (mostly, it's the latter), so they never really got to drink their hearts out together.
