Now that's what I call saved by the very last inch
Or kilobyte, in this case.
Had the sim failed just seconds sooner, he would have been a goner come Monday. Had this happened the week before, he would have been a goner come Monday. Had his superior left ten minutes before, he would have been a goner on Monday.
Sure, he might have made a wrong decision, but he got just incredibly lucky after that.
Good for him.
