You are saying all this based on zero working knowledge of operations in the industry you are commenting on

I don't need to have worked in the funeral industry to know that just cold-calling businesses and asking the first person who picks up the phone if off the top of their head they feel like they had a 10% increase in business over the last year isn't valid data that you can base a conclusion on.

Get back to me when you have real data, Because this isn't going to convince any skeptic and is therefore useless.
