All credits to you for referring to both these guys. About the functionality test, Hafiz Sb didn't do it in front of me but I requested him to check the meter in detail.
Due to the traffic and parking situation of saddar and complete negligence of Corona SOPs at Plaza Market I planned my trips as Touch and Go. Was In and out of Plaza in hardly 5 to 10 mins which included waiting time at Hafiz Sb's shop
