Not a dumb promo actually - unlike RedLobster
Chicken is of course relatively cheap - and getting cheaper with bird flu outbreaks.
BWW IS designed for guest to stay extended periods - and if your drinking alcohol - it’s highly profitable for them.
Plus let’s say average AYCE’er puts away 15 wings - how does that compare to the price of just walking in and buying 15 ? Guessing it’s basically break even. Better for the restaurant than someone buying 10 getting 10 on their regular promo for off nights.
Myself - I wouldn’t do it - but I’d be lucky to eat 8. Also not exactly a BWW fan - ok for a chain - but plenty of local places better.
