Am I right in being mad at my friend for this?

Last night my friend (I'm a guy) and two other girls took a cab to another college about 6 miles away. We went to go into this frat party and they wouldnt let me in without and id and I realized I forgot my wallet. When i told her, she just said "try to get in" and went inside, leaving me stranded in some random college with no money or id. I eventually found some kids that I knew that went to the college and we drank for a while then they said I should get going because the bus system shuts down at 2. I get on the bus and it only takes me part way there. Another bus never came so I walked 2.5 hours in the dark back to my college in flipflops semi-drunk. I know it was my fault for forgetting my wallet, but she could have just gone to a different party where they weren't checkin ids. Am I right in being mad at her? We always hang out and we were supposedly best friends before this.
