I think Premier has a standing policy to not spend money on promos or advertising. They literally don't need to now that they've established a name for themselves as the place to go to get what guys want. The 50k was probably viewed as a gamble. If they could knock out their biggest competitor and make Flirt lose the tons of money they invested in their spa, then it's a cheap victory. As it is, it's bitter pill for them to swallow but they will recover.
if it was to knock out competitio is was a stupid gamble.
if they won their income would still be the same. sure it would have been a hit to flirt as they would have lost money on the renos. flirt could sell the second body rub licence if they had to recoupe the reno costs immediately. or open a new location with more modest trappings.
if they lose they are out court costs and look petty, foolish and afraid of competition.
