Now you all know how some balls with lots of top spin will drop down and catch the line .... Now we have a guy in a recreational mixed doubles match group that calls the balls 'long' before they hit the ground. My male partner and I today both were positive that two were definitely not out. My partner finally asked him to stop making calls before the ball had bounced. I was serving and finally said sort of kidding "next time I'll take the point as you are not supposed to call 'out' before the ball lands" He appears to be the sort of person if he made a mistake he would not take it back and just pretend it was still out. ugh! What do you all do in a situation like that?
