As pointed out above - that rule doesn’t necessarily apply to all bets - only First Set wagering.
There is nothing “natural” about a void on retirement in tennis. It’s completely book by book. Lost many a wager when someone was up big and an opponent retired - only to see wager voided. Experienced tennis bettors know which book voids following first set completion, which books void with ANY retirement and which ones consider all bets action once the match begins. Hopefully not too expensive of a lesson for you - but book could be well within their rights to grade as a loss - especially if they paid winners.
Bookmaker is usually the one who gets most complaints as any retirement voids all wagers - not just totals and live bets. Similar to their rain out policy on baseball (which is another rule unique to them).
