People need to work not to show off to clients

Worst experience.... Ruined my day...Manager or the person who is in charge a coloured lady with a scar on the upper lip has a stinking attitude. Was busy explaining her my problem about renewing my bank card she just walked away. Then I had to ask her why did you walk away she was telling me that I wasn't listening to her that's why she walked away. What kind of a service like that where by employees just walking away from clients. Its as if they are not there to do their jobs but just to show off to us.
