Long wait in unsafe environment

Lunch time at the store a total of three cashiers working. Express line even longer. There is a maintance team busy hanging signs from the ceiling. The broken ladder which needs to be supported by one of the team memebers is positioned in the que. Customers are forced to walk under this ladder trolley or not. While the guy is putting hooks into the ceilig dust is falling on people and the products. I confronted the manager but had to tell him what to do as he did not seem to think that this was wrong only \inconvenient"in his words. Very unprofessional and uncaring way to treat customers. Don't think I will go back to this store."""
