Emily has her own coffee shop business 'Emily's Coffee'. She operates the business from leased shop premises on Queen Street, Brisbane. Prior to this, she used to work for an established coffee chain 'Felicity's Coffee' that sells coffee in physical shops in every major city in Australia.

The coffee business of Emily's Coffee has been very profitable since it commenced trading 18 months ago. Emily has had to employ additional workers in order to keep up with customer demand. Greg is the latest addition to the team. He works as a full-time barista at Emily's Coffee.

One day, Harry (a walk-in customer) orders an iced latte and is served by Greg. Harry pays for his drink and immediately takes a few sips of the contents. He sees a cockroach moving in the midst of the foamed milk and immediately faints. As he collapses, his head hits the cold hard floor. Fortunately for him, Greg who witnessed the entire incident takes him to the hospital. Harry is now in need of extensive medical treatment and rehabilitation in order to lead a normal lifestyle again.

It was later discovered that Greg had not been clearing out the rubbish on a regular basis. Rubbish discarded for weeks overflowed from the rubbish bin in the kitchen. As a consequence, many cockroaches could be seen roaming about. It was likely that a cockroach had found its way into Harry's drink when no one was looking.

REQUIRED: Advise Greg whether he has any possible remedies under the law of negligence. Refer to specific legal cases and/or statutory provisions to provide support for your answer.
