From MonsteraDeliciosa, Tales From Retail:
Our store has a large area of high-end patio/outdoor furniture. It's comfy and lovely and it had better be, for the price! So Friday afternoon the owner calls down to the front desk with a really good question-- what's up with the guy asleep on a couch back in patio furniture?? A staff member went to check on him and woke him up: "Oh my god, I'm so embarrassed! I'm fine!" Five minutes later, he is not only still there, but asleep again. A different employee went this time, and "WOW, this is embarrassing!!!!!" But... he still didn't get up and leave. At this point, the staff is huddled in the next department whispering and wondering... and then we realize that he is ASLEEP AGAIN. Finally a third person went back there, woke him up and stood there until he got up. Then he wandered out the door and into the sunshine.
Sleep disorder? Narcolepsy? Allergy pills? We will never know, but seriously, you can't just sleep in the store. It's weird.
