Dollar Tree review: customer service and satisfaction

I was on my way to Dollar tree like I always do after I come out of the gym, but last night when I got to the Dollar Tree I got stopped by the security guy saying that I will be banned from the store and maybe even trespassing because my car was making a lot of noise (my car being street legal race car, the car is heavily modified so it's a little bit loud) he said that people were complaining when actually people were taking pictures of my car like they always do, and asking me for social media info of my car. I love this location and I love how the employees treat me and greet me when I come to the store every day from Monday to Friday, but after last night I'm afraid you may have me and my friend's business... that's not how you treat a customer and even worse you don't stop a customer on the way in front of everybody like if he was a criminal just because they drive a $100k+ car that is heavily modded and makes it a little loud.
