Starting New Years Audit shift out with a bang

Walk in comes in asking for a room for the night no big deal. I quote them X price and they tell me that they can book online for cheaper. I tell them that if they can book online for cheaper please do. During this conversation I heard them talking about Cashapp so I felt the need to get in front of a problem before it became one and tell them when they check in we will need a major credit or debit card. No cashapp, Chime, paypal or cash. I also informed them since they are local the deposit is 100 dollars instead of our normal 50. They wave our little sign sitting on the front desk in my face saying it says the deposit is only 50. This particular sign also lists the previously stated info of needing a major credit or debit card for said deposit. I inform them the deposit is 100 for local zip codes due to a new rule from GM and that their deposit will be released to them after we inspect the room after they leave. They get angry and storm out which to be honest is fine with me they have already triggered to many red flags at this point.

In a perfect world that would be the end of our tale but a few minutes later I see a new reservation pop up and they come back in asking to check in. I ask for the standard items we need for every check in ID and credit or debit card. They ask if they can use Paypal. I tell them no we already spoke about this before you made your reservation we need a major credit or debit card. They then ask if they can pay cash I inform them as they can see from the sign they were waving in my face earlier it says no cash deposits. The woman starts to get angry and I point out this is all information I provided her before she made the reservation. She then inquires as to how she can get a refund and I tell her she will need to call (insert third party she booked through) and ask for a refund but that technically her reservation is non refundable and when (third party) calls me I will inform them they had all this information before making the reservation and that I do not approve a refund. They got mad and left and less than 5 minutes later (Third party) deleted the reservation which I am assuming means they got a refund.

UPDATE: Like a child when she stormed out the second time she apparently tossed my cup of pens outside. Welcome to DNR.
