dripping blood all over the carpet

I brought my laptop to the Beverly Hills Public Library because they have air conditioning. Upon entering the building, I scratched my elbow against a glass case. I've asked several employees for a band-aid and not one of them could help me. There are no first aid boxes in the whole building, apparently. I was instructed to walk across the street to the police department for help. I mean, really?!?! How about purchase a box of one hundred from the ninety nine cents store.
