Stop, T...?

I was walking through an urban neighborhood with a very intelligent Australian. A tall fellow walked past, My companion raised his voice and said," Sir!"
The fellow stopped to look at us.
"You still have the store tag on your sports jacket," my companion said. The fellow turned his left wrist to see, and sure enough, there was a store tag sewn on his sleeve.
"Otherwise you look fine," said my companion.
The fellow gave us a look of distaste and hurried on his way. I can't help wondering whether he had just shoplifted the jacket.
