Family Dollar review: customer service

This evening one of the employees told me I need to hurry up because they were closing. The time at that moment was 9:37 p.M. When I was not in compliance, the older woman working the register... Her name started with a k I believe, slammed my money on the counter verses handing to me since I didn't leave the store before 9:50 p.M. She also told her coworker to lock the doors before other customers walked in.in which they did walk and the woman at the cash register cussed and called the customers names under her breath. This behavior is completely baffling seeing as though I am shopped at various family dollar locations and have never had a bad experience until this evening.
