Address: 144001

Sir am from jalandhar.
Today i was at pspcl office boota mandi.
I was standing in queue and infront of there was 1 person. He was paying his bill after his turn when i was going to pay my bill then suddenly the cashier (Vinod) closed the window and sayed that its a lunch time but 2-3minutes were left. I sayed please take my bill i am giving payment by check it will take less time for you. Then he refuses to take bill and started taking bills from inside his cabin from people standing in his cabin. When we sayed him that you are taking bills from people inside his cabin he started miss behaving.
The cashiers name is vinod at boota mandi branch.
