Billionaire Harsh Goenka joked about L&T Chairman SN Subrahmanyan's 90-hour workweek and 'staring at wife' comments during his company RPG's townhall meeting. "Last time [Subrahmanyan] spoke in townhall, he got into lot of trouble. I've not spoken about Sunday working...staring at your spouses," Goenka joked. "I regret I'm unable to make you work on Sundays," Subrahmanyan had said.
