I plan for that happening, and it does irritate me sometimes. I have had people kicked out before. One time was when a group of teenagers kept horsing around, throwing balls all over the place and in one case throwing a ball so hard to where it cracked a sweep when it was down. The front counter then turned off their pair and were told to not come back.
The other instance was when a big family was doing one of those $12 for 2 hrs unlimited bowling at an AMF house. That is worse because most of the AMF management never cares- they just want people packing their houses. In this instance, the family had kids running around all over the place and kept trying to take my 2 lanes that I paid for. They were getting in my approaches, touching my equipment and even being nice and telling them to stay on their pair didn't work. Eventually, they were thrown out after they did the same on the opposite pair as well. The only reason is because I know the staff there since their pro shop drills my stuff.
I just plan for it and I'll take extra time during shots as needed. I just try to keep a level head about it, and it does help with focusing on what I need to do. This helps when it comes to league nights.
However, if you start going on to the pair of lanes I paid for, touching my equipment, and being a total jerk, then that's a whole separate issue. I will make it very well known to management if being nice doesn't work. Even more so if it becomes a safety issue.
