My ebt was lost a week later it was used at a market can i ask the manager if i can watch the video from thier security cameras to see who u?

You can always ask but most stores will not allow the public to view the videos. The best thing to do would be to file a police report on the missing card and report that it has been used recently and tell the police where the bank is showing it to have been used. Police can go a lot further than you could legally

You would have a much better chance of being made whole by using the tools available to local & national police agencies and the bank's security groups.
