Dollar Tree review: Staffing, customer service

While shopping at the dollar tree in Tempe on Kyrene and Baseline, the manager on duty was complaining to her staff about how much work she had to do. Every other word out of her mouth was the F-bomb, how do they expect me to do my job with two truck deliveries in one day. One register was open, the line was super long and she looked over at it, rolled her eyes and continued to unload boxes onto the shelf. The cashier called for back up, she looked over again and rolled her eyes and waited until someone else walked up to assist. I visited the store again today, I wanted some balloons and when I asked the same manager for assistance, she said what number told her a green, white and gold balloon she repeated what number. Act like you like your job, provide customer service and not use profanity. Worst experience both times I've shopped at this location, definitely will not return.
