SINGAPORE – What is good customer service worth? It’s a bit like asking how long is a piece of string, but one real estate agent who went the extra mile for a customer found an answer: around $200,000 for an hour’s work.

Unlike some agents who judge the propensity of people to spend based on how they look or what they are wearing, this agent chose not to ignore a lone, casually dressed customer who wandered into the showroom.
