When customers complain that can really hurt you from progressing. Customers can be very mean and people don't understand that they can potentially cause harm to family's. Publix takes customers complaints very seriously. I have a family of 4. I've had a few complaints in the past cause people don't like waiting their turn and they like to cause a fuss at the customer service counter. I work in the deli. Very difficult customers love the deli. If only people weren't so hateful. More love. Less hate. If your not careful you can lose your job over some hateful person who could care less if you end up on the streets.
