Il Messaggero reported that the Belgian couple were enjoying a romantic dinner in the at the restaurant Trattoria Casanova in central Venice on Monday when the man raised a problem about the way his steak had been cooked.
Although staff hurried to change the man's steak the tourist still refused to pay – causing an argument to break out between the tourist and the waiting staff at the restaurant.
Allegedly, during the argument the tourist was set upon by three or four of the restaurant's staff.
“In a flash the waiters had thrown him to the ground and were kicking and punching him,” Il Messaggero quoted an eyewitness as saying.
Following the incident the tourist was taken to hospital, accompanied by his wife, where he spent the night in accident and emergency after sustaining a black eye and broken teeth in the attack.
“The waiters reacted badly and violently,” the witness told Il Messaggero. Police are investigating the incident, which was captured on CCTV.
