"The customer is always right" that's definitely not a Thai saying,
but my father instilled it into me ,and that how I ran my businesses,
obviously they weren't always ,but you had to let them think they were,a
lost customer ,is lost money , If it cost something to keep them happy,
OK you could always find a way to recoup it, ,with a lost ,unhappy
customer ,you lost their business and could harm your reputation.
