A missed opportunity.
If I had a customer in distress (melting ice cream is a minor distress
) I would try to win them over rather than shun them.
So instead of having a customer that only used one of my services, I would show them how great it would be to use all my services. Then they would go around teling stories about how I helped them out of a jam, instead of how I let them down.
But not everyone runs their business like that. It's their business so it's their choice.
