Why does my if statement not print? python [closed]

This is my code. it is an easy program but I cant figure out why it doesnt print the last lines?

drink = input('What is your order?')
if drink == 'beer':
    age = int(input('What is your age?'))
    if age >= 18:
        print('Here Beer')
    else:
        print('No beer for you!')
        if drink == input('Do you want water or juice?'):
            if drink == 'water':
                print('water for you!')
            elif drink == 'juice':
                print('Here you go some juice!')
