The Walmart Dilemma!

I leave my house once this week to go to Walmart for some late night frozen pizza and I take my family with me. We park and as I step out of the car there is a dude (not homeless) approaching me saying something I could really make out...as he got closer I realized he was saying, "Muhbuh cha liffnuh ga ba!" I'm sure he understood himself, I ignored him and didn't make eye contact with him because Drugged out people creep me out! When someone is strung out they have a tendency to have retard strength and are completely beyond reason and very unpredictable and now he was hanging out right next to my car! So after we were safely inside Walmart, we alerted the manager that they have a shady drugged out dude (who was now directing traffic in the parking lot next to my car) outside making their customers uncomfortable. They didn't really do anything about it so I checked my pocket to see if I my knife I always carry at my hip...no knife, my son normally has at least 5 knives in his pocket for some reason...no knife...my wife normally has a pocket knife...no knife! So we get our pizza, and to tell you something about myself,I've ALWAYS been a great problem solver, and I used to be full of piss and vinegar and ready to throw down at any point, but, these days, I'm a lil' more evolved and fighting sounds like a pain in the ass, not mention I am quite passive aggressive nowadays! So, what I decided as we neared the cashier was to tell my wife to hold our daughter, and told them not no make eye contact with him and to just ignore him and get in the car...(my plan was if he approached me and I felt threatened, I was prepared to punch this dude in the stomach as hard as I could, and leave) I knew that if he was drugged out the pain wouldn't bother him, so trying to fight would be out of the question, what I would need to do is physically put him out of commission long enough to get my family safely in the car and home...luckily when we got to the car, he was inside yelling nonsense in front of the store as if he was an angry standup comedian and I didn't have to deal with him. Now my acid sack is full of pizza and getting ready to do some more art for these shows I'm doing in TX, which I'm leaving for tomorrow!
