White male I've had pretty standard experience:

Where are you coming from? - Country X

What was the purpose of your visit? - Business

80% of the time they will ask what I do - depending on the customs officer this often results in a conversation about my line of business. As I use this as an opportunity to promote my products and services I actually prefer when they ask. I've handed out several business cards though I've received no calls (to date) as a result of these interactions.
