I tip when i meet an exceptional service orientated individual in almost any "service" orientated business........ i as a professional have often received "tips" or as we like to call them "bonuses" or gifts of appreciation from a satisfied client.
When someone is really happy with "work" you have done for them or saved them months if not days of work, the client often shows their appreciation. Tipping should be purely based on the work done and your overall satisfaction.
