Behind the Card Shop Wall Discovery

I was with my mom, sister Jackie, and Nikki. We were driving back from some event, maybe church or something, and we were driving by this big card and game store, video games and things. I got them to make a pit stop so we can pop in. We went in and it was a huge warehouse-type, just like a really big building. On one wall they had all of this really cool art and a brick wall set up, with just really cool art set up on this wall that had TVs embedded into it and game shrine-type stuff, just part of the wall. Clearly there was something behind the wall to make this happen. We ended up finding the owner, this old Asian guy, who said he could give us a tour. I guess every once in a while he gives tours of what is behind this wall. He took us back there with a few other people and started showing us around. The first area was very dark behind there, but there were sewing machines and some beds and cots set up for, I guess, his family or other people to come and sleep here if they needed to. Then there was the wall with all the things behind it, like the backs of the TVs and the setup that displayed out in the front of the wall. We kept going into different sections of this whole other world behind this wall. There were tons of boxes of cards and big display things and all sorts of other little setups, other people doing work over there, like sewing or just moving merchandise around. It was really cool and he had so many old CRT TVs that were set up that were connected to, I guess, online. They were hosting servers with those. It was very cool behind the scenes for just what seemed like a normal card shop. We left and the place and it was in business for so long that it said in faded paint above the entrance, "We're in every Toys R Us. Check us out there." I don't know what they sold to Toys R Us but that must have been a while ago. You could see the building was a big square but then also connected to this big house, which is just part of the big building, which I guess is where the family-owned business all lived there and everything. Then we went back to my mom's car, a Honda Pilot, and when we were getting in some woman came over and opened the hood while we were in it and started flipping switches and stuff. I got out and yelled at her and she kept doing it. I saw her take something from the hood. I went over and pushed her or something and I don't know how it turned to this but I started punching her and she wouldn't give the thing back. She wouldn't give us the car part so we threatened to call the cops and push her down but she still refused to give the piece back. I think she ran away or something. I felt bad for punching the woman but she was a thief and stealing our shit.
