Vasan Eye Care Hospital — Unethical behaviour of the Staff in Specs Section

I have went to Vasan hospital in Madurai By-pass road before a Week back for General eye check-up ; felt unhappy with the staff behavior as she was very rude, she was taking care of specs section . if we want to buy specs is it a compulsion to buy there only ???we have informed we will check other option also ;but she said y r u wasting our time by coming here ? only if we buy specs alone we need to come

is it the way will u behave with the customer ? i want a proper solution for it
