I'm sure it was Haas's wife. Tarango accused an umpire of being biased at Wimbledon in 1995. If I'm wrong I apologise to Mrs Haas lol.
Wimbledon Takes a Slap in the Face : Tennis: Tarango becomes first to walk off court, then accuses umpire of favoritism.

WIMBLEDON, England — A quiet day of tennis turned bizarre Saturday, when American Jeff Tarango was defaulted after walking off a court during his third-round singles match, then later accused an umpire of fixing matches for other players.
In a remarkable postmatch news conference, Tarango, of Manhattan Beach, made several serious and at times rambling accusations against chair umpire Bruno Rebeuh of France, whom Tarango called "corrupt." In another strange twist, Tarango's wife caught up to Rebeuh after the match, confronted him and slapped him.
But I'm now off to google Mrs Haas as well! lol
p.s Angie it is on Youtube! (tho haven't found the wife slapping bit yet, must be somewhere am sure it was shown on tv at the time)
