Canara Bank — Misbehaving with Senior Citizens

In our Mangalore usually senior citizens are given respect and help but my parents had a horrific experience in Canara Bank Kadri branch of Mangalore. My dad who is 70yrs old was made to stand in long line to draw money and finally lady staff tore the check and started yelling at him. If there is a process then they can explain in respectable way. Instead she yelled at him even though he never said anything back rudely. My mom had leg pain she too was made to stand in line finally the staff at cash dispenser counter tore the check and yelled unnecessarily.
