tourney mucked hands and jerks question

[sledghammer]

my biggest pet peeve in poker is when kids ask to see my hand at showdown, after calling a river bet.

just wondering...

in a large multi tournament, are players still allowed to ask to see mucked hands at showdown? my largest pet peeve is guys asking to see my cards, and personally it seems unreasonable in a tournament, where collusion is virtually impossible.

also, has anyone tried to fight this rule in an obviously non-colluding hand? like when the hand was heads up from preflop? after reading tommy angelo's article about the rule in particular, i've been even more pissed off when people pull that [censored] in cash games.
