That's absolutely infuriating - a 40% rent hike justified by one pani puri stall is beyond ridiculous and feels like pure exploitation. Your anger is completely valid, especially when landlords use vague "development" claims to mask what's really just opportunistic price gouging. It sounds like you're dealing with the harsh reality of how quickly housing costs can spiral in growing cities like Bangalore, where any tiny change gets weaponized as an excuse for massive rent increases.
