I'm not sure if any of these are covered:
1. The One Word Orders- These are the shoppers that don't bother saying "Hi" or "Excuse me" to get your attention, but just walk up to you and say exactly what they're looking for. "Eggs!" "Milk!" "Greeting cards!"
2. The ones who don't care if you're listening unless you ignore them- These are the guests who will ask you for things ("Where are the eggs?") when you're either:
a.) Across the aisle from them and unaware that someone is speaking to you
b.) Busy assisting another guest or team member
c.) Aren't even FACING each other.
My favorite (not at Target, but most of these have happened at both jobs, so I'm sure it's only a matter of time):
I was working as a personal shopper at a grocery store when a 'guest' and I were standing back to back. I was selecting items from the freezer; she was looking at peanut butter. I heard her say something, so I turned around. Her back was to me, so I assumed she was either talking on the phone or she was talking to herself. So, I kept working. She, then, (without even turning around) got mad at me for not answering her question.
Bonus:
3. The customers at OTHER stores who get mad at you when you don't help them out when you go shopping immediately after work and forget to take off your TARGET nametag. I went shopping after work, and since the store I went to was right next door to Target, I just went straight there. A woman started asking me where something was, but I didn't pay attention because 1.) I'm off the clock 2.) I don't work there. She got mad at me when I wouldn't help her, and when I pointed out that I don't work at that store (the uniform and nametags don't even look the same, plus I had my purse and lunchbox on me, so I clearly wasn't working), she got mad at me for that.
(I swear, you can go into Walmart in your red and khakis and people will get mad that you're not helping them).
