Dollar Tree review: poor customer service

I was in lane 2 next to get rung up when the lady said she was closing. I was sent to lane 3 when lane 2 reopened. I asked her if it was next in line she responded that they don't do that and laughed. I told her you just sent me away not even 3 minutes ago. She than said you have to wait there i already called people over. Once I was finished getting rung up in register 3 I asked her for her name (Nitasha). She said there's my manager do whatever you want. Not professional what so ever and rude...
