Dollar Tree review: Rude manager

The manager Grace at the Dollar Tree by Renton Walmart, is just rude! I went over my budget forgetting the prices went up and tried to remove 2 items at first, but then having to remove another 3 items, which the sweet cashier had to get the manager to come over to do. The manager started with an annoyed look and when the cashier told her what help she needed with, Grace (which her name does not describe her), sighed out loud and said "wow" really disgusted. I asked "please don't make me feel bad than I already do" she replied "you don't understand that people can lose their job for this" I replied with, "no I do understand and I am sorry" as I am standing there with people around me tearing up and trying not to lose it. I kept apologizing and the only one that said anything was the man behind me saying "it's ok, don't worry about it" "I hope you have a great rest of your night". I won't go back to that location anymore. She should be ashamed treating people the way she does.
