While the cold weather is bad news for some, certain businesses benefit from the sub-zero temperatures.
According to owner Debra Jensen, Black Hills Bagels Expresso in Rapid City was busy all week long.
"We've been doing a lot of hot chocolate, a lot of hot chai, a lot of mochas that kind of thing," said Jensen. "It's funny how some people will come in and they'll say could I have it extra hot?"
Locksmiths have also been on their toes this week, at least in a different kind of busy.
"It definitely changes when we get into these extreme cold weather spells," said Harvey's Lock Shop Manager, Bruce Dedic. "We see a definite shift from maintenance and installation to a repair and access."
Dedic says helping people get into their cars and homes is something he's used to this time of year.
"Vehicle locks are in a constant state of freezing up, ignitions, doors, trunks, it really doesn't matter," said Dedic. "We do a lot of quick short jobs, we're gong out on location getting that customer into their cars and it doesn't matter if it's noon or midnight, we're out there in this weather doing it."
Automotive shops and tire installation businesses are also experiencing a higher volume of customers.
"It's right around double right now with the cold snap that we've had," said Advanced Auto Repair Manager, Josh Wahlberg. "Doing a lot of batteries, charging systems, a lot of customers without heat with the vehicles."
And of course hardware stores are picking up, as many people will need snow blowers, windshield wipers, and more.
