The more interesting bit is that the payment issue was between Satyajit and Saif"s business partner, Dinesh Vijan. And Saif was not exactly fighting with his trainer. In fact, Saif and Satyajit had a long history together and it was he who recommended his trainer to Aamir Khan for Ghajini who in turn asked Rani to consult him.
Satayjit has been helping Saif to develop a lean physique for his next movie Agent Vinod. He was even risking offending Rani by paying more attention to Saif. But problems started when Dinesh, Saif"s co-producer for Agent Vinod, defaulted on Satyajit"s payment.
There were too many unpaid bills and Satyajit had no choice but to leave. Satyajit of course confirmed whatever transpired but Dinesh said that he discontinued because he went out of town.
That"s speaking like a true businessman, especially a B-Town one, a world where cheating, manipulating and lying is the order of the day.
