Someone asked the Knower Of All Things about Dunkin's Retreat, which in its previous incarnation operated on SW 6th Avenue near Pine Street. The front half was a cafe. The back half was a cardroom, in which the habitues played poker and panguingue for small to medium stakes. (This was in the 1960s and early 1970s, before the Transit Mall forced the business to move.) Its owner was Johnny Boston (a nickname because he grew up in Boston, though he was born in Argentina), a restaurateur who liked the occasional friendly wager.
One day the government closed the cardroom and charged Johnny Boston with promoting gambling. Some minor penalty ensued, and the card games ceased. He sold the business and it moved to 11th and Washington.
The same state that righteously prosecuted Johnny Boston for promoting gambling now runs video poker games and sells scratch-off lottery tickets. Johnny went to his reward 20 years ago, but the odds are 7 to 2 that he's looking down and laughing.
