What do u think of this behaviour of bradman during his playing career?

Bradman had a quiet, solitary off-field demeanour that first drew comment during his performances on the 1930 tour of England. Melbourne journalist Geoffrey Teb, described Bradman's aloofness from his teammates in his subsequent book about the tour. He described Bradman's usual routine after play - Bradman would retire to his hotel room, write and listen to a phonograph. After scoring a world record of 334 runs in the Test match at Leeds, Bradman was given a cheque for ₤1000 by an admiring expatriate Australian businessman. Teb wrote that Bradman had not even offered to buy his teammates a round of drinks, let alone share the money.
