When the river was dealt, John blankly looked at the cards and raised his bet. An obscenely large amount.

The casino is quite quiet, it is not a very expensive establishment, but it is not cheap either. People around behave decently, enjoy drinks. John takes a swig of Scotch, looking at you defiantly.

When you call, he smirks and reveals his cards.

"Straight flush, lass/lad. Ye'll hae better luck next time, mayhaps."

You realize it's a loss. You only have a straight.
