I reckon he brought his own chips for three reasons;

1. Looks like the reds on the far left have inserts in the picture. The ones that went to the poker room do not have inserts.

2. Ive never seen a rack that big in real use (only behind the cage). It would be too wide to fit a normal table.

3. It looks like he is holding the rack upright. The ones on the tables are bolted and locked to the table.
