A Name? Or a Noun?

The lovely Robin made me buy a new pair of shoes last night. Cruel, yes. But I forgive her. 

At one point as I was trying on one pair, I heard her say, "Bob, these shoes have your name on them." I thought she was speaking metaphorically. She wasn't. I refused to buy them, however, since the possessive apostrophe is missing, which makes me think they didn't even intend the shoes for me.
