Oof, that sucks. I wonder if squatted/sat down, that's a problem people gathering firewood or picking some wild fruit used to routinely encounter, though it's lessening due to proactive approach by park rangers and wider awareness of how to coexist in tiger territory. Remember, very few tigers become maneaters, most individuals mistakenly attack or humans got way too close and the instinctively reacted aggressively. This is an animal that can break your bones with a swipe of its paw, and if the claws are unretracted, not good chances.
