Bending handed over the cash which was a "considerable amount" and probably over $1000. Then they tied him up with a 10m computer cord and left. Bending said they didn't tie it very tight.
"I moved my arms and it fell off, then I rang police immediately."
Today Bending felt "numb" to last night's incident. He was waiting for the shock and fear to kick in.
"I don't know when I'll drop a glass and lose it. I'll be cashing up and there'll be a noise and it'll all come floating back.
"I've never had anything like that before."
Bending had been a bartender for 23 years but had worked at the Huapai Golf Club for one year exactly on January 11.
Bending thought the men were under 30 and one was the leader. He was the one who did most of the talking.
"One was calm and assertive. The other two followed what he said."
The golf club has insurance and will be beefing up their security measures, Bending said. They were going to change things so no person is cashing up alone anymore.
Acting Detective Sergeant Jackson Shewry from Rodney Police said the offenders threatened the manager and took his wallet. They also took a sum of money, cash boxes and the golf club tip jar.
The employee was then tied up and had his face covered.
Shewry said the offenders had their faces covered with bandannas and wore black hooded sweatshirts.
Police have today carried out a scene examination at the property and a number of inquiries are under way.
