When there is ten seconds left he starts the countdown and I protest telling him that he should count in english instead of french since the guy clearly dosen't speak the language. Floorman goes "trois, two, one" and between the two and one the non-french guy throws in a pile of 5k chips putting the other player all-in. Other guy SNAPmucks putting his hand over the line and after five seconds or so the non-french player turns over A7o for a complete bluff, and this is where things starts to get crazy.
This depends on the rules of the tournament really. If it was stated that it was a dual language event of French and English then fair enough - otherwise it is being held in a French casino and everything should be in that language. English shouldn't really be allowed during a hand as it is up to the player to know how to play in the local language.
Good luck getting English or US staff to count down in French at one of their events.
