Should is entitled b---- get her money back ?

When you work with the public you will always get one who will be a ruddy nightmare.

My manager frequently tells me about the customers who rile him.

Restaurants don't refund half the money a customer pays for their meal. It's all or nothing. And if you're throwing fits over somebody complaining about their order being wrong, and you're trying to justify it by accusing them of mumbling, you should get out of the pizza boy business. Maybe go back to being a mall cop. You're stupid enough to get rehired.

Wow. Perhaps your customer service skills need some adjusting.

If you can't make any more sense in real life than you do in this question I can see how you cause problems. Ever heard of the saying "the customer is always right?" That's how businesses are run, and the reason is they want to make a profit and have repeat customers, not drive people away. If you can't work with people maybe you should find something else to do.

You were in the wrong for throwing a fit and blaming the customer. You're lucky you weren't fired outright. She deserved her money back in full thanks to your unhelpfulness and attitude.

thats up to the manager to decide

I am so sick of working with the public.I mean how much of a con artist is this lady.
