I was serving and hit a service winner. opponent then complained that I hadn't cleared a stray ball on my side before serving. so the service winner was nullified. (I was unhappy about the demanding tone the complaint was delivered in. had the tone been less righteous I would've been less ticked off. I also didn't rush the first serve so there would have been ample time to mention the stray ball before the service winner was struck) whatever, I never argue about a play cause it isn't worth the hassle. I line up to hit a second serve and...you knew it was coming. Ace. lol.
