Casinos constantly put in stupid trips and twists into promos to frustrate and annoy customers to not use, its basically bait and switch.
A lot of promos for new users are a pain or come with a bunch of weird obscure rules. Remembered there was a promo in Bally's AC for a free buffet, but you had to wait 30 minutes after playing with your card. WTF, I'm sitting at a table for 5 hours, then I have to wait half an hour for a buffet?
Good for the litigants. Unfortunately I guess it didn't go far enough, the casino management should be put in jail for their bait and switch tactics.
