Wimbledon Championship
Paramount Club in London's swish, Haye as he Wladimir Klitschko chose to put its members behind them.
He has always maintained his 31st birthday in October before he resigned.
Although the sponsors of the booth and the man insisted that it was not an official retirement party, he has advised him not to box again.
He believes that former world champion twoweight is nothing left to prove.
Booth, who is Haye's trainer and manager, previous night said: "Personally, I don't think he should fight again.
"He doesn't need to. He has achieved all he could achieve in his career so he can retire with his head held high.
"People must not forget he's a cruiserweight who fought a dominant heavyweight and so there is no shame in losing on points to Wladimir."
He added: "We are having a party. But I would not say it is an official announcement that he is retiring.
"David worked very hard for the Klitschko fight and he just wants to enjoy himself."
Haye has admitted they are unlikely event of a rematch with Klitschko to have agreed to postpone their retirement.
