The felt
Felt is brushed in one direction, from the dealer outwards, with a soft brush kept for the purpose. A damp cloth is used for marks, never a wet one, and the cloth is changed on each table. Once a week the whole surface is rested under a dust sheet, so that the nap can recover from the hands that have rubbed it.
The cards
Decks are replaced long before they show wear. A card that bends, marks or picks up a stain is removed, and the whole deck is retired with it. Oliver counts each deck in and out of the box, and a sealed new one is opened at the start of every evening, so no two nights share the same cards.
The chips
Plain chips are wiped with a damp cloth and left to dry in their trays. They are counted into stacks of twenty and sealed at the end of the night. The chips hold no value and cannot be sold or exchanged, which makes the counting a matter of order rather than of money.
The wheel
The roulette wheel is oiled once a month, levelled with a small bubble level and spun empty to listen for any sound that does not belong. The ball is kept in a velvet pouch. Oliver says a wheel that sounds right plays right, and he has not yet been proved wrong.
