As per the title....
I have just read the now (sadly) locked thread of Gaffers regarding the above and agree wholeheartedly with its initial sentiments.
We had similar whilst at the Scottish Police College with dining in nights, proper full dress, passing the port, speeches and toasts etc etc etc. Afterwards, all off to the large comfy lounge with (Chesterfields?) couches, the open fire and nightcaps. Many a capture was retold to a varied mixture of surprise, understanding, mickey taking and my tale is going to be taller than yours...

Also, similar to Gaffers to be had by me as but a plooky yoof in the Merchant Navy. Proper dress for meals in the saloon, duty mess hovel if in a boilersuit, upstairs into the bar for brandy and medals afterwards.
Main theme through all the above is....
We talked and discussed matters with common interest, disputed things that annoyed us (sometimes quite heatedly...) but, most importantly, understood and made allowances for all sorts and never to adopt any moral high ground against another, and particularly to never make assumptions as to the person.
Conversation.... Great stuff....
