The Nun,
Bizarrely, Ive had similar at Salford.
Definate split pot and the chips went to the other player....by the time I screamed the cards were all back together to be shuffled for the next hand. Prob my fault for not shouting quickly enough but I hated the game for a good few days after that. Despite thinking it was my fault the person in question was well aware of what the problem was and refused to speak to me or anyone else on the table.
In your case, the guy refusing to let you know what chips he had left beggars belief......am I wrong....dont you have to have your chips clearly on display at all times?

Dont blame you for being pi**ed off...been there and I was too.
