Consider the following premises. For all x_19, x_19 is not a cashier. For all x_19, if x_19 were fast, then x_19 is running. For all x_19, if x_19 drinks water, then x_19 is happy. For all x_19, if x_19 were a bartender, then x_19 is happy. There is at least one x_19 for which x_19 is a cashier or x_19 is fast. For all x_19, x_19 is a bartender or x_19 will drink water. Can we infer the following from them? For all x_19, x_19 is not happy.
 From the fact that there is at least one x_19 for which x_19 is a cashier or x_19 is fast, and that for all x_19, x_19 is not a cashier we can infer that there is at least one x_19 for which x_19 is fast. Finally, from the fact that for all x_19, if x_19 were a bartender, then x_19 is happy, that for all x_19, if x_19 drinks water, then x_19 is happy, and that for all x_19, x_19 is a bartender or x_19 will drink water we can infer that for all x_19, x_19 is happy, which contradicts that For all x_19, x_19 is not happy. Therefore, the answer is no.
