Guests that don't finish their sentences or ask valid questions. OR, guests that give me WAY too much irrelevant information any time I ask a simple question, thus making their transaction last way longer than necessary. THESE people are the bane of my existence. I hate it when I get a guest who comes up to Guest Service, and they don't know how to articulate the need they have, so they'll say something like....
GUEST: "I got this as a gift." (pause)
Me: "Okay, so would you like to return it?"
GUEST: "Yeah."
Me: "Okay, do you have a gift receipt?"
GUEST: "No, but it was too small, and it was raining today, and carrots are purple because I have a grandma."
Me: "Kaaay, well can I see your ID?"
GUEST: "Okay" (pause)
Me: "I need to scan your ID for the return."
GUEST: "Oh." (few minutes pass while they browse through their disgustingly unorganized wallet or purse that is an accurate symbol for the idiotic chaos they must live in)
Me: "Thank you. Okay, so that's going to give you $20, on a gift card, okay?"
GUEST: "Oh well I just want another one."
Me:
