Bangalore Metro Rail Corporation — waiting time in metro station

Address: 560030

I was waiting for my wife at the yashwanthpur metro station. Doing so I skipped two trains. That's when two security guards came upto me insisting that I can't wait at the station if I have missed two trains. I understand the security reasons behind this, but as I was genuinely waiting I told them that I was waiting for someone and if it is a rule I will, but requested them to show a copy of the rule or a board that says so. In the absence of either I refused to vacate. They then got their manager who started off calmly then lost his cool just because I kept insisting on the written rule. He created a big scene and threatened to hold me back.and all this happened while my wife had arrived and we were ready to go.below is the exact text on the metro website

Overstay Rule: A passenger holding a valid ticket can exit from same station within 20 minutes and from other stations within 120 minutes. For overstaying in paid area of Namma Metro beyond these limits, penalty of Rs.10/- per hour is charged subject to a maximum of Rs.50/-.

I was well within my time limits. So I ask if there is a rule I will oblige. But put it up somewhere. Let people be aware of it. In this day and age Don't expect citizens to blindly agree to any rule verbally communicated by a person in uniform.
