Mexican is hanging around the 2/5 game for no apparent reason. Mixed race guy in the 8 seat (sporting matching white Air Jordon shirt and hat, flashy gold watch, sunglasses, and tied piece of string for a bracelet) slips chips off his stack to him. He takes the chips across the room, briefly visiting the adjacent tables. (Imagine the singing reluctant groom from The Holy Grail tentatively walking toward the window to shoot his message out the window to John Clease.) He walks up behind the 2 seat (older native of Guam wearing a Tony Hawk hoodie) and deposits the chips on top of his stack.It could have been as innocent as a red/black prop bet, but I didn't like the vibe. Based on the conversation, the dealer clearly knows the 2 seat from outside this room. I cashed out, explained the situation to the floor, and left.
