Sadly just this week. Only a level 3, but I have thrown out as high as second place at East/West. Neither were really gym related (booster stuff), but the manner they approached me wasn't acceptable. I will not be verbally assaulted in my gym or anywhere else for that matter. I learned many years ago to get rid of them ASAP, because it's only a matter of time anyway, so why drag it out and let them disrupt you or your program. No one likes to do it, but it beats the heck out of the alternative.
