I hate customer service jobs

I hate customer service jobs. Get someone who makes a reservation in the middle of night and demands their room at 2:30 AM. I am sold out tonight. The res they just made for today is good at 3PM, not 3AM when my guests are still sleeping (I am not yanking guests out of bed to give someone a room). Well had 2 reservations from the day before arriving and I checked them in. Now I am racist cause he's black and this is going on social media. I explained those people had reservations from the night before and I have to honor them past midnight. If their reservation was for yesterday, I would have gladly honored it at 2 AM. But it wasn't, it was made for today and the check in time is 3 PM. They explain they are from New York and unfamiliar with such things. Yeah, I'm sure hotels in New York have check in times too. They scream at me how heartless I am cause they have a little girl and I am throwing them out in the street (not exactly, I let them sleep in the lobby and let them use the public restroom I also let a homeless guy use while they're screaming at me). They were welcome to eat from continental breakfast when they were still waiting for the manager at 6 AM. I texted the manager to come early cause they were still here and not leaving until they spoke to a manager. I began doing my work from the back room to avoid them. The cook came in for breakfast and kept screaming my name at the front desk to tell me things. I explianed I am working from the backroom. Manager came in 15 minutes earlier than usual and I explained the situation. People were much calmer by then and asked for the uber number. Manager even made copies of their cancelations to prove they weren't being charged for them.
