Lack of Customer CARE. Mean Cashier

Till number 24, Juanita as per my invoice, was so mean, lacking customer care... After paying all my items she kept quiet and let me like that with my items on the counter. She was not interested and kept quiet letting me to see for myself what I do with the items I bought. I asked her any plastic bag? She said I didn't say I want a bag!!! As a sign of courtesy, the expectation is to ask the customer if they want a plastic bag or not.. In her case, she felt it that it will belittle her to ask me if I need a bag not. Instead she cared less leaving me wondering thereby the counter with my items.. Indeed she showed lack of customer care..
