After that "loosely written" QFR several years back, a lot of the 20 to 30-somthings in my area became pretty liberal with "cheers-ing" as we call it. I know the CO (and maybe a subsequent QFR) has tried to dial it back since, but that genie's not going back in the bottle around here.
Most of us won't do it in front of most J-dubs over 45, but it's pretty common for pints of beer or drinks to be raised/clinked when we're all out celebrating something....a new job, turning 30 (that's different than celebrating birthdays, right? ), St. Paddy's Day (oh wait, I mean "hey look, the bars are all open at 10 a.m. today. Weird. Let's go!"), or when we just all happen to be out around midnight on Dec 31st.
