Dollar Tree review: cashier was so rude!

When I approached the register there was no cashier standing there but the light was on as well as 3 employees standing right in front of me talking amongst themselves. Then the cashier Sandra walked up to the register with a Box in her hand opening it I stood there for about 5 minutes while she was opening the Box my stuff was already on the counter to be rung up so at this point I have been waiting a good 10 to 12 minutes and she stood in front of me still opening a Box after she got it open she proceeded to ring my stuff up didn't say a word to me and then continue to repeat hit the green button hit the When there was nothing on my screen for me to hit it took a few minutes for it to pop up once I hit the green button I looked up and she was shaking her head and just Saying my goodness my goodness. Needless to say I guess I will not be shopping there again I have never experience horrible customer service like that at that store so it definitely caught me by surprise.
