Staff displaying bad behavior. Review on D Mart, Hyderabad

This incident happened at shaikpet demart hyderabad on March 13 2024 timing 4:30pm..After I had finished paying my bill and was leaving the store, at the exit asked me to take off my cap. She checked ot thoroughly and then questioned me, wondering of i had stolen it because they sell similar items on the first floor. I assured her that i had purchased the cap myself from outside local vendor since their establishment did not carry that specific material. She mentioned that she would review the CCTV footage. I responded by saying that she could go ahead and check because I had nothing to hide, as I hadn't taken anything from her store that i considered to be a low quality. The price for the cap they are selling is only around 100 to 200rs. I understand that it is part of their job to check everyone at the exit point., but there is a proper way to approach customers and ask then to come aside without insulting infront of others., the behavior of the staff at the shaikpet branch near Tolichowki hyderabad on March 13th, 2024 at 4pm was very unprofessional.
