Moltmann shops at Kmart

I bought my copy of The Crucified God in a used bookstore, and there's an inscription inside the front cover.  It was a birthday present from "Care" (Cara?  Caroline?) to Sharon.  This is the exact message:

Dear Sharon, The only thing I know about Moltmann is he wrote about 'hope' and he shops at Kmart and buys gee your hair smells terrific and fruit of zee loom underwear!  Somehow this seems like a dullard of a birthday present - but I hope it's (it was) a happy - I love you, Care

The big question is: How does Care know all this?  Here are some theories:

1.  Care was a cashier at Kmart and sold Moltmann shampoo and underwear.  But how would she know who Moltmann was? 

2.  She was a theology student and worked part-time at Kmart. 

3.  But then what?  Moltmann lives in Germany, correct?  So he's in the States for a lecture, stops at the local Kmart for some necessities, and coincidentally a theology student who would recognize him rings up his purchases?  "Oh, Dr. Moltmann, I attended your lecture yesterday, and by the way fruit of the loom underwear is on sale today."

Something about this inscription is begging for a short story - it has my imagination running.
