I had a Karen at my local swimming pool, she was a total b*tch, she argued cuz her kid was "7" years old and apparently she left her kid there before (I overheard their conversation) AND HER KID WAS 7! The pool rules says: "Children under 8 cannot be in the pool WITHOUT adult supervision" so I walked up to her and said: "Shut it, they said you can't so stop whining" and luckily a cop was right next to her and what she said was this: "I will f**k*ng kill you in your sleep you little bi*ch a*s motherfu**er" so that cop was right next to me when he heard that and she was taken straight to jail lol, also due to her leaving her 7 year old son in that pool, the pool administrators actually BANNED her from taking her kid to the pool for 4 months (Basically a year in pool term) (Cuz summer is only 3-5 months)
