Given the option of standing in the rain or ignoring a man in a hi-vis vest and standing under shelter, I know I'd be remaining dry.
Ha ha! You'd remain dry until the fuel poured out of the wing and you were covered in kerosine. Then you'd be in the local A&E. Trust me, I've seen it happen more than once. (This is why you shouldn't stand under the wing).
