How do you know?

Studies already suggest that 9 out of 10 people prefer text communication with businesses. Of the remaining 10%, we have to establish that they:

1. Prefer the phone over other alternatives. Some may want face-to-face communication, for example.

2. Want to phone a utility in the first place. Preferring phone communication over other means does not imply that they want to communicate.

3. That the person of which you speak knows of them. Someone who really does want to phone a utility, but is not known by said person, would not meet the qualifications defined.

Unless you actually compiled a list of those he knows and surveyed them in a good faith standing, you can't know. The statistics are not in your favour, though. It is quite unlikely that he does know someone who wants to make a phone call to said utility. Perhaps your weird nerdiness has clouded seeing that?

No, we don’t have to establish that he knows them. It doesn’t matter if he is right about the people he knows: he is wrong about the customer base and the business decision.
