I don’t know this for a fact, but I don’t believe the woman standing in line in front of me wanted to discuss the last haircut you got for five minutes before you took her order. Yes, she was wearing the uniform from one of the mall’s hair styling salons, but rather than signaling that she wanted to discuss the last haircut you got, to me that would have signaled that she didn’t want a conversation having anything to do with hair on her lunch break. And you know what, you could have thanked me when I gave you the dollar back after you handed me two fives, a one, and three quarters and said “Your change is $10.75.” Finally, I apologize for getting a touch testy when you handed me a small coke instead of a large coke and then tried to cover up for it by saying “That’s the size coke you get with a regular combo”, but I really wasn’t willing to overlook that statement particularly because you had just told me my order took so long because of the large fries I requested with the jumbo-sized combo. I almost said something to your manager, because he was standing right beside me out front restocking napkins and ketchup, but I figured I didn’t have to after he looked at me, rolled his eyes, and shook his head when your response to my statement that I had paid for the king-size combo was “Oh. That’s right.” You tried to blame your overall ineptitude on somebody's order fifteen minutes prior to my visit - "I'm sorry," you said, "but I've been flustered ever since that guy wanted cheese on his sandwich" - but I'm betting flustered is probably the way you go through life, not a one-time thing.
