Death's probably coming for you now. So you're going to have to kill the next person in line and break Death's order. This is the only way to win.

And congrats. Your brain worked in a way where you noticed a person's tilted angle and their collision course, and you subconsciously noticed something wrong with the milkshake (smell, saw how it was being prepared, etc.). Either way, in the world, quite a few one in a million chances happen all the time. I mean, with all the people in the world and all the times a 1/1,000,000 chance happens, it's going to eventually happens, even if you don't notice.

Anyway, why are you even bugging about it? Nothing you can do about it if it is supernatural.
