If you are sure the sale is small in nature and would be a waste of your time, by all means turn that customer over to someone who can speak their language and go to the next customer.

When you are selling this should give you a hint when someone puts on an act of being superior or arrogant. Customers who seem intimidating are sometimes the biggest spenders.
