The Thai Cafe had a box of sensitive information from past employees. Since it is a $150,00o fine to dump the information in the trash they knew they needed to have it shredded. This is where it becomes unclear.
The box turned up in a dumpster behind a school. It was found because so many people dig through the dumpster that the school makes sure nothing important gets left for thieves. They notified the local news.
The owner of the Thai Cafe said they contracted with someone to destroy it. I don’t know if they tried to hide it in the schools dumpster or just left the box with someone who didn’t shred.
Any reputable shredding service will provide you with a certificate of destruction. This lets you know the job was done correctly.
