It also use by customers to get what they want.
Just yesterday, a guest called and asked to return 3rd night stay because it was more than the 2nd night room rate. Guest booked the room online and had a confirmation email with a daily rate, signed a physical registration card that shows daily rate during check in but insisted that we are overcharging him. He thretened us with a chargeback.
I returned the money because fighting chargeback is a losing battle for us.
They booked 8 rooms as a group, and I basically told him, that they are not welcome here next year and he should explained that to his group why we won't let them stay. Also told him, I am going to call everyone in his group and tell them not to book at our location.

A couple weeks ago, bank called and wanted to verify the charge. Bank wanted to know if the charge was valid. I told them it was charged through chip reader, and I have a video of the guest using the card. She is like, thats all I need. I m going to deny the chargeback.
A lot of guest book room, and when they forget to cancel they use chargeback.
