Were they right to refuse delivery to me?

i used to order from this place often and I even gave the delivery people a lot of tip. So today I call in and this 8itch picks up and asks me if im sure i want to order because it will take one hour. By her tone, I already knew she did not want to deliver to my place. She then asked me to tell her the new address which she made me repeat like 4 times as if she could not hear me. She then told me to hold up so she could talk to the driver and after like 2 minutes very rudely says we dont deliver there. funny thing is the delivery people deliver here all the time and its only 3 miles away from the restuarant. I felt like cussing her off at that instant and call her all kinds of names, but i just hanged up on her 8itch *** because I done that before to some other person and it felt like crap. However, all I want to know is can I sue this 8itch for denying me service or were they justified? I mean what the f9ck did I do wrong for this f9ggot 8itch to treat me like this? I usually have a very calm demeanor and treated the delivery guys nicely and tipped those f9ckers too. those f9cking italian b9st9rds
