Ah, crap. Please don't tell me the casino checks are already bouncing. I deposited mine on Fri and my bank held $900 of the $1100 pending clearance. On Mon or Tue this week the rest posted to my account, but I know that banks must post held funds within 2-3 days regardless, but that it can still bounce and be reversed later. I'm seriously hoping yours was from a different bank/account than mine.
And here I was about to make another withdrawal of a similar size...
