It would be nice if you hung up before you called me names

I'm working at the hotel tonight. Up until about 30 minutes ago things were going fairly smooth and quiet. And then a customer came to check in. While I was checking him in, the telephone rang. So, I said just one moment and transfered the line over to the reservations desk. We pay to have that convenience, and at times like this when I am busy checking someone in it is a true blessing. I no sooner finish checking the guest in and the phone rings again. Same dude as before. He began to yell and curse at me for transferring him to reservations! I apologized to him. He continued to get louder and more irate. I apologized again. He rather loudly pointed out "I'm an F***ing gold member". I apologized again. At which point he said I will take my business elsewhere but not before I have you fired. I apologized again and this time was able to get in the words, would you like me to take your reservation now? NO and then you hear the phone fumble and right before the line clicked dead I heard the words that have me so upset and brought me to tears...C*** Whore.

What did I do to deserve this? What could I have done to avoid that? I thought I was doing the right thing by not having him wait approximately 5 minutes while I finished checking the other guest in! By the time I finished checking the other guest in, he could have had his reservation made! I feel belittled. I feel dehumanized. I feel crappy. I feel like I need a root beer float.

I can't wait for 11pm to get here so I can go home. Hopefully I will never have to run into this guy again. I am too good to be treated like that. Whatever you have going wrong in your life, pleae don't take it out on me.
