Is This Anything?!

I got to the post office late today. Fortunately as I fumbled with my packages, Julie Butler let me in. Once I queued up, the elderly gentleman with an "I Vote Pro-Life" button at the end of the line who had his two dollar bills, and maybe some coins too, out and ready to make his purchase, offered me his place in line because "You look busier than me, and I just have to buy some stamps." I said, "You can stay. You won't be taking much of my time."

I ask my most intelligent readers, Is this anything? Is this conceited or arrogant or just polite?
