There is an analogous situation in (e.g. sports) betting. Every now and then someone places a really long bet on something like Leicester winning the Premiership and then gets a collosal payout. Inevitably there's some naive speculation that the betting shop will be very unhappy with this. In reality theae u likely events happen relatively infrequently (often disproportionately to even their long odds) and the publicity from such an unlikely win more than makes up for the payout.
