Totally concur...although you have to be very careful where mourning is concerned. Balance things with the needs of the family to grieve and for workmates to raise a glass and then get on with what we do.
When its my turn can you just arrange for the bar to be opened (on my mess number) free beer all round, everyone pissed and saying "what a top bloke Pete was" ....
and then get back to work the next morning with massive hangovers and let that be the end of it.
