bad customer attitude

i was at pnp little falls in wilgeheuwel doing my monthly shopping and i took a bottle of wine.there waa no ribbon put to indicate that they closed the wine section.when i got to the till the cashier lunka just told me she cant put through the wine indicating that the bottle store was closed.i asked her as to why was the bottle section not cordoned off if there is a time limit as the customer now ends up like a fool. she referred me to her manager whos only response was to say sorry about that and then he goes and attend to someone else.very unprofessional response for a manger as if took the timeto explain i would have understood.by just telling a customer sorry about that is very unforsessinal and now you make it the customers problem for someone who shops there regularllly. i did not mind not taking the wine as i woud have understood but i can't stand unprofessinism as i am support the store.
