I hope to be in shape

My family has lived in this town for four generations. Our jewelry store is a fixture in the community. All I heard growing up was how our friend’s Mom bought his mom’s engagement ring from our father or Grandpa. I’d see our teachers come in to the store to get their watches repaired & neighbors shop for birthday & holiday gifts. I always knew I’d join the family supplier after university & eventually take over from our father. What I didn’t guess was how the challenges I would have to deal with would be so different from what Mom & Grandpa faced while I was in their time in the store. They had to deal with the occasional shoplifter or someone passing a exhausting check. I have thieves trying to chop in through the air duct. I’m not kidding. There are some every enterprising criminals willing to try anything to make a fast score. We have visible security measures that have always worked as deterrents! But now, when the criminals see cameras & alarms, they just take a different route & chop in through the Heating & Air Conditioning system, but getting in through air conditioner & heating air duct is easier than you think. If you have air vents, you’re an self-explanatory target. That’s why I’m upgrading the security system & incorporating Heating & Air Conditioning burglar bars as an obstacle for exhausting guys cutting in through the ventilation system. The bars are put deep inside the air conditioner & heating ducts so if someone should crawl in, they’ll get stopped at a point where backing out is impossible. The police or fire department would have to extract them. I can’t have a store without heating, cooling & ventilation however if the component bringing the heat & cool air in also lets in thieves, I have to secure it somehow.
