I usually have positive experiences here, just picking up the occasional package for my business. Interactions are usually quite positive. However, this morning, I had an interaction with an employee who was quite obstructive. I didn't have my tracking number and kindly asked if we could look it up by either the sender or recipient. The answer was immediately "no, we can't do that." After asking again, and giving her my name, she immediately hopped on the computer and stated, "I can't find it." After I saw the package on the shelf with my name on it, I said, "let's double check the spelling" and spelled my name and she found it. Then she proceeded to ask for address verification of my office, which was fine. But the obstructive tone in which she asked was inappropriate. I understand that she was following procedures, but in terms of a customer service aspect, I found this to be a negative experience to start the day. Why use obstructive tones/language, when it doesn't cost anything to be positive and encouraging?
