Dollar Tree review: personnal cell calls by employees

On April 3r, 2011 I was at the store purchasing about 15 items and there was only one cashier line open. When I asked if another clerk was going to open, she (Liz sales associate) proceed to tell as soon as she got off the phone. By the sound of conversation it did not seem she was on a business and I did asked her but she just wave me off then I mention that I would call the manager only then she said to the person that she would call later. I wish I could e-mail the company because this is not first time. No longer a customer of Dollar Tree!
