On the season premiere of the show, D.C. Housewife Lynda Erkiletian explained that she refused to work with the America's Polo Cup -- a yearly charity event organized by Salahi -- because according to her, "nobody got paid."
Now, TMZ has learned a small embroidering business just won a legal battle against Salahi -- in which they claimed dude never paid up for work he ordered for the event in 2008.
According to the lawsuit, filed by JB Printing & Specialty Services, Salahi ordered a whole mess of customized embroidered polo jackets, fleece blankets and straw hats back in 2008 ... but never paid a cent of his $4,576 bill.
Salahi had a date in a Virginia courtroom on the matter just last Friday -- but he didn't show up ... so the judge ruled that he must now fork over the dough.
Last we checked -- JB Printing was still waiting for their check.
