Doesn’t Understand The Custom Part Of Customer, Part 5

(I work at a somewhat upscale clothing store. Lately customers have been coming in and refusing to even acknowledge my greeting, let alone let me help them.)

Me: “Hello, welcome to [Store]. What can I help you find today?”

Customer: “I’m not telling you what I’m looking for.”

Me: “Okay. If you need anything let me know.”

(Customer proceeds to look around for about 20 minutes. I check on her several more times. She lets on that she is looking for something specific to wear to a graduation. She will not tell me what it is.)

Customer: *leaving* “Well, I guess you just don’t carry cardigans anymore!”

Me: “Yes, we do! They are right here on this table! What size or color would you like?”

Customer: “White, medium.”

Me: “That was pretty fast, right?”

Customer: “Sorry, I just didn’t want you to try to SELL me anything.”

Me: “Then why are you shopping?”
