McDonald's

I asked the cashier Mayra (she has a long tattoo across the length of her left forearm to her elbow) what the price of the largest drink was and she responded by saying $1, I paused for a second when she rudely prompts me by asking if I want her to guess the type of soda I want too. Guess the type of soda I want! I was infuriated! Who does she think she is speaking to me like that! As if she had a grudge or some sort of vendetta against me! I responded with "I would like you to work on your customer service skills" to which all she said was "Ok well we have different varieties". Completely ignoring what I requested. I told her my choice of drink and at the window after paying my total I asked her if she could let me know how to put a customer complaint to which she only said "You can speak to my manager, she's at the other window" and then she just simply shut the window. Upon shutting the window I saw her walk over to her manager who was handing over the food at the second window and I could see her discussing something with her, most likely giving her a heads up about me. I told the manager about the situation and that Mayra needs to work on her customer service skills to which the manager herself all she really had to say to me was "Yeah, she shouldn't do that". I told her that I have intentions of submitting an online complaint to which she had nothing else to say. The least she could've done is have Mayra come up to the window (since she apparently also has the liberty to leave her post as a cashier whenever she desires while there was still a long line behind me), and have her apologize, after all she has time to warn the manager about me. All in all McDonald's store # 4439 does not care with a lousy leader for a manager and Mayra should not work serving the public!
