You toucha my chippies, I breaka you fingas!!

Nuff said?
Why would a card room allow something like this, which over time can only lead to problems?
The only time I would do/allow such a thing would be, 1) if I asked the dealer FIRST and was given permission and 2) the other player agreed. Even then I would carefully stack the chips so that everyone was absolutely sure it was correct. If the other player is absent, it is up to the dealer to make change.
Now in a tournament, if a seat is empty, no player or player absent, and it is that players turn to post blinds from a position that is awkward for the dealer to reach that players chips, I have posted the blinds, but again ONLY after getting permission!
In general, it is not a good idea to touch another players chips period!
