Staff at tills did not want to help me because store closed 1 minute ago

<p>Went to MRP just before closing time, took some stuff to buy etc.</p> <p> </p> <p>So when they started closing the doo, went to the tills where the staff did not want to help me because it is past closing time (1 minute).</p> <p> </p> <p>Best of all is they could not tell me sorry sir, we are closed, they just stood there looking at me shaking their heads and lifting their hands, which is rude and inapopropriate. I had to ask them are they going to help me before I got a verbal response.</p>
