While in the store, talk to Doug, who suggests going outside to look around. Agree and go with him if you already picked up the remote control from the Employee area and looked at the photo of the employee. If not, do these first. (Thanks to Zedarboy for the info about the employee photo).
Go outside. Look at the guy trapped under the telegraph pole over the road. Use the remote on the TV shop opposite. Then use the axe on the gate lock and pick up the brick. Use the brick on the TV shop.
