Restrooms

You can assume that gas stations along the highways outside of town will have a bathroom available, but this isn't true of every station in L.A. itself. Restrooms in parks are often dirty. Restaurants and bars may have signs that read "For Patrons Only" so that you're obliged to buy something to use the facilities. Better bets for relatively clean, obligation-free restrooms are those in department stores and large chain bookstores.
