Barney: Last winter, I slipped on the outside stairs of PineTree Café and broke my leg. My fall was caused by ice on the stairs that the restaurant failed to remove. Since the restaurant clearly did not provide a safe atmosphere for its customers, I am justified in taking it to court.
Lydia: Unwarranted lawsuits are sweeping the country—lawsuits that have no legal merit and are brought simply to make lawyers and their clients rich. If this trend continues, soon our legal system will be swamped to the point where it won’t be able to administer justice to people who truly deserve it. You therefore should drop your case against PineTree Café.
