This hand happened several years in the Nor Cal area. Still wondering what should have happened.
There is a flurry of action culminating on the turn, where villain checked, I bet small to induce, villain x-raised almost all-in, I 3-bet all-in. The river is quickly dealt, the hands were shown, and I won (full house vs. a very weak hand). The dealer now did the accounting, and discovered there was $35 left for villain to call which he attempts to collect and then villain says "I didn't call" [this is correct] and refuses to pay the $35. The floor is called.
What should the floor do in this situation?
