I love this thread!
A few years ago at our local Walmart, there was a woman working at the pharmacy that just looked like she would bite your head off if you breathed in her direction. I couldn't find a particular item and she was the only one on the floor that wasn't busy with another customer so I had no choice but to ask for her help. Well....let me just say that before I could blink an eye, she became even witchier than she looked!

You would have thought that I just kicked her in the shins really hard! I had been polite to her, and I even smiled at her but to no avail. I've worked retail many years in my life and I thought, you know, her supervisor needs to know how she is treating customers. So I made my complaint and walked away. I don't think the employee knew it was me and I don't even know if the supervisor spoke with her or not.
So, here we are a few years later and this woman still works in the pharmacy department. Since that's where I get my meds, I have no choice but to have to deal with her. I always make sure I smile and am pleasant. I refuse to let her lousy attitude get to me. Lo and behold, some months ago I was wearing my Eeyore t-shirt and she smiled at me and said Eeyore was her granddaughters favorite! Go figure LOL. So we struck up a bit of a conversation and she actually smiled and was sociable. Ever since then, she smiles when she sees me, asks how I am, I ask her how her granddaughter is doing and it's all warm and fuzzy.
Amazing what some patience, smiles and something in common can do for a relationship....no matter what kind of relationship it is!

I have no idea why she is so grumpy all the time. But it makes me smile to know we can help each other out now.
