I think what may confuse some viewers is the name "Casinos Austria" - and when they see chips with the US$ they assume that those US$ chips are used as casino currency in Austria. A "50" on a chip from Austria is 50 oS (Austrian Schilling) and the official language of Austria is German, not Austrian.

At one time (still may be the case) the entry fee into an Austrian casino was about 180 Austrian Schilling paid at the reception. In return, the purchaser would receive chips marked with 20s which were not able to be exchanged for cash. A system which would probably not be too popular in Las Vegas.
