Dollar Tree review: customer service

I was shopping at the Punxsutawney Dollar Tree around 8:30pm, the store is not supposed to close until 9pm. An employee came up to me and told me to take my items to the register because they were closing the store. I did not think it was appropriate to basically kick me out at 8:30. I put my items back and walked out of the store. Thanks to that employee this store lost a sale.
