Thank you for the Dean Martin/Foster Brooks memory lane bit.
Dean Martin could be exhibit A on society's change in attitude towards drinking. (and smoking for that matter).

In the 80's, I was going through new hire ground school at an airline that hosted "beer call" on Friday nights at a bar near the airport for us newbies. A few line pilots would drop by to hoist one with us.
My opinion of the practice is neutral, but can you imagine any airline doing so today?

The times changed in more ways than Dylan anticipated.
