The best restaurants serving Pizza pasta food in East Walworth Southwark London

I ordered a pizza, paid for it, waited 10 minutes for it. The man who took my order, went up to another customer with my pizza, saying what type of pizza it was. I told him i ordered that pizza. He said nothing & gave me the pizza. I ordered my drink again, he came back with the wrong flavour, i told him what flavour again. After eating my pizza i noticed i wasn't given any tissue with my order. I had to wipe my hands on my jeans & leave oil on my lips. Why is there someone serving customers, who is almost deaf &/or doesn't understand English properly?
