MELBOURNE (Reuters) - An Australian “prankster” barmaid who served a patron a shot of disinfectant has appeared in court over what her lawyers said was a “misguided” joke.

Melbourne barmaid Emily Craig, 23, served a client a single 30ml shot glass of Pine-O-Cleen disinfectant in March during a 6 a.m. drinking bout at Evolution Nightclub, causing him to become violently ill, the Melbourne Magistrates court was told.

“This was a misguided joke at an ungodly hour,” Craig’s lawyer George Balot told the judge, according to reports on Tuesday in local newspapers.

Police told the court that Craig “was known for her prankster-style behavior” and once covered a bar in sticky tape. She “upped the ante” with her pranks by serving up the powerful floor cleaner after giving the man shots of pure water.

The patron developed ulcers on his skin after drinking the disinfectant shot from Craig, who has since lost her job and faces four charges of intentionally causing injury.

The case was adjourned until February.
