Ah that's no fun. Maybe something like a quant sending a message to his mistress to get out of his vacation home because his wife is on the way, but the wife is cheating on the quant with the CEO of one of his investments which is the firm that's doing the FTL communication, and the signals get mixed up so the CEO the quant both arrive at the office, ready to go, and meet each other there and it's really awkward.
