Reliance Fresh — working hours and the staff's attitude

Being a regular customer for reliance fresh outlet located in avadi (Poonamallee high road) reached around 2.00pm (Current working hours is 7.30am to 2.30pm) the person in the entrance said we are closed and only serving for the customers who are already in.
From the glass doors i noticed there is no customers at all and managed to enter in in to the outlet, one customer paying the bill and leaving the outlet at 2.05pm (Store managers can verify billing history)
I requested the staffs for pick up few grocery items with in 5 minutes which is very much needed for the current situation and the products we cannot get in small grocery shop which is open now (03/0/2020)
A group of staffs are sit together fun themself and replying me if you even pick the item the counters are close and we are not willing to bill you.
The worst experience never faced in my life the management should training the staffs for at least basic customer service.
A customer is the most important visitor on our premises. He is not dependent on us. We are dependent on him. He is not an interruption on our work. He is the purpose of it. He is not an outsider on our business. He is part of it. We are not doing him a favour by serving him. He is doing us a favour by giving us an opportunity to do so. ~ mahatma gandhi (2 october 1869-30 january 1948)
