Parent is saying they are a customer shopping for holiday/business destinations and they decided to to do business with HK. In other words, HK just lost a sale.
This is just pure pedantry, because your whole argument would become null if the parent said "potential customer" instead of "customer".
I would consider it null already, given that the parent described their situation very explicitly, and it is clear as day that the situation implied "potential" in "customer".
