Manager Resham Singh came out of the office in time to see the robber run from the store. The whole episode took less than 20 seconds.
"These situations happen everywhere. We just have to be alert all the time," Mr Singh said.
He said the robber was prepared. "He was a very fast man. He was ready for the mission. He might have run up the road. Someone was probably waiting there to pick him up."
The man, a Maori or Pacific Islander, was 1.8m to 1.85m in height. He was wearing dark clothes and running shoes.Andrew Koubaridis
