(Note: This business sells plug-ins that release scent when a bulb is inserted. Some of the plug-ins are nightlights; most are not. This takes place around the beginning of fall.)
Customer: Honey, which of these are nightlights?
Me: Hm, looks like the snowflake, the owl, and the pumpkin.
Customer: And these? Are these nightlights?
Me: Nope, those are regular. The only ones that are nightlights are the snowflake, the owl, and the pumpkin (I wind up repeating this several times over the course of the interaction).
Customer: Okay, I want something PLAIN. Which ones are the plain nightlights? I gotta replace this one. (Holds up a plug-in she apparently wants to exchange.)
Me: (internal sigh) The pumpkin. (Points.) The snowflake. (Points.) And the owl. (Points.) Those are the only nightlights we have right now, ma’am.
Customer: Never in all my life has it been this way here. My mother and I come here all the time, it’s never this way.
Me: I’m very sorry.
(Another customer approaches and grabs a plug-in.)
Customer: (under her breath) I can’t believe that just happened.
Me: I’m sorry?
Customer: She just came right up and took the one I wanted.
Me: That wasn’t a nightlight, ma’am.
Customer: THAT’S THE ONE I WANTED.
(Eventually I managed to slip away, but I wound up getting pulled to cashwrap just as this customer and her mother were ready to check out. She complained several more times about the lack of appropriate nightlights and even tried to get a discount without a coupon from my manager. We ended up giving it to her just to get rid of her.)
