Pothys — Unacceptable behaviour of staff in supermarket

Hello sir, I have a happy customer of Tirunelveli pothys until today since I had a very bad experience in Chennai pothys' supermarket. I asked way for mt basket to pass on where a staff member is arranging tomato. I insisted her to move and make way and she denied, and I asked her patiently again, for that she replied very rude that naan thakaalila irunthu vilagi pogava, nee suthi poga vendiyathu thaana.now she touched my ego using nee, so please make a training to the staff members and teach them to behave to their customers. We also accept that they are working hard to feed their family, but touching our ego also triggers me, so please do the needful and teach them manners.
P.S : I never had such issues in Tirunelveli and the reason why I choose pothys over other shop is our loyalty to the shop.
