Case 1
Gasim comes to the Laboratory to do some investigations urgently. He gives the blood sample and is asked to come to collect the report at 2.30pm. Due to some reason he was unable to come at 2.30pm and came at 3.00pm. When he comes to the laboratory counter he finds that there is only one girl at the reception, and she is busy attending a patient. The counter is crowded and Gasim is unable to give the report collection slip. After a few minutes he is finally able to get near the counter and when he gives the Report collection slip, the girl looks at it and asks him to wait and gets busy attending another patient. After a few minutes when Gasim still didn’t get the report, he asks the girl whether it is not ready. The girl then asks his name, and tell him that it will take some time. She then takes the report collection slip and goes inside leaving the counter empty. A few minutes later she comes out and tells Gasim that one test has to be repeated
