I think "Fancy a pint?" is the quintessential British reaction to ~anything~ actually...
"I had a crap day at work"
"Fancy a pint?"
"I had a great day at work"
"Fancy a pint?"
"My girlfriend dumped me"
"Fancy a pint?"
"I won the lottery"
"Fancy a pint? (Drinks are on you)"
"My leg fell off"
"Fancy a pint?"
Pints are big and solid and comforting and take a time to drink during which you can calm down and reflect.
Peace
