A shoplifter is someone who takes things from a store without paying for them.
When we talk about shoplifting, it usually means that someone has taken merchandise from a store without paying for it. This can happen anywhere - at a supermarket, department store, or even a small boutique. It's not just one person taking something worth a few dollars; it can be a serious crime if the items are expensive or there's a lot of them involved. For example, you might hear about a case where someone took a bunch of designer clothes from a high-end mall. The store would have to investigate and figure out how the theft happened, and maybe even install security cameras to prevent it in the future.
