There have been a string of robberies this year in Sioux Falls already.
Sioux Falls Police Officer Sam Clemens says it's not very often weapons are actually used during a robbery.
More often than not, they are shown as a threat. That's what happened in these most recent armed robberies.
However, it was just a little over a month ago when a shot was fired during a robbery at the Cubby's on 49th and Western.
"Well they just came in and asked for the money and as she gave them the money then they were walking out -- the one guy turned and shot. So it was scary for her," said Mary Aadson, Manager of Cubby's.
Mary Aadson has been working in convenience stores for the past 14 years. Although she wasn't working at the time of the armed robbery incident, she says it could have easily happened to her.
"It could happen any shift. It doesn't mean just overnight," said Aadson.
Sioux Falls Police Officer Sam Clemens says local businesses are taking steps to help prevent crime.
"They have good lighting. Some of them may lock their doors when it's dark out or late in the night," said Officer Clemens.
And look up at Cubby's and smile -- because you're on camera.
"The surveillance stuff is great on the backside if something happens because we have a nice record and some of the images we can get are incredibly clear and crisp," said Officer Clemens.
Since the armed robbery at Cubby's, security has become an even greater priority.
"Now they'll keep one door locked instead of both of them open so they know exactly when people are coming in. The main thing the company tells us is give them what they want and get them on their way. Just get them in and out of here," said Aadson.
Aadson has no doubt that those committing these robberies will get caught.
"They think they can get by but they're going to make a mistake at some point," said Aadson.
