At our public park, we have a sign posted that reads, "Please Limit Play to One Hour When Others Are Waiting."
My interpretation of this rule is that nobody should be made to wait longer than one hour (unless there are multiple groups waiting in line behind one another, which is rare.)
I noticed many players interpret this sign literally, in that you are not allowed to be on court more than one hour in total if somebody appears and starts waiting.
To me, this encourages poor court etiquette, with pushy behavior and players approaching people on court to ask how much longer they plan to stay and even how long they have already been playing.
If I first approach players on court to ask if they will be much longer, it's only because I'm deciding whether to move to other courts and I make sure they know I'm not trying to push them off.
If I'm waiting, I like to wait on a bench in front of the courts, so they don't feel anyone is hovering. At 40 min. or so, I will politely ask if they plan to play longer than 20 min. more simply because many people are not even aware of the sign/time limit.
I'm only asking because a very aggressive group of pickle ball players barged their way onto the court while it was still in use, even though I told them it was still 20 more min. wait time remaining.
I first noticed a lady waiting at 7:25 pm and set a timer for 60 min...she said later that she had arrived at 7:11 pm, fair enough. But at 7:50 pm, with the doubles set finished and two players deciding to rally, they stormed the court with their nets and decided that we were finished. (Later, one of their group said they had arrived at 6:30 pm and they were waiting in their car, which I don't think counts as waiting.) Any number of people could be waiting in their cars, etc. You have to at least be reasonably visible, that only makes sense, right? Their logic is that you get one hour, and then you're gone. It doesn't actually matter if anybody was waiting for 59 of those minutes, but since they happened to know our schedule, or saw us when sitting or even just passing by in their car, they know we've been playing for over an hour. Cue the interrogation and accusations, rather than simply wait one full hour.
I've waited a full hour countless times, and to me that is the only logical interpretation of this rule which seems to be straightforward but it still easily misinterpreted. Even if you can't agree, nobody should ever barge onto the court without even having a discussion and agreement. If I were in their shoes, I would have waited an hour. If any group intentionally disregards this rule and continues to make others wait one hour+, I'll just do the same to them next time. But you never storm the court like a commando and just take the court by force.
(Btw, these "ladies" didn't get to play their pickle ball and preferred to call the police instead of waiting another 20 min. Nobody ever came...understandably. And one of their wiffle balls is now in the big oak tree lol.)
