in my experience, every business gets some form of cold calling be it farming, catering, interior design, automotive. Those cold calls can be by phone, email and in most cases, in person.I think unsolicited calls, either in person by reps or over the phone are totally disrespectful to farmers.
No one would walk into a businessman's office unannounced and expect him to stop what he was doing just to listen to a sales pitch.
Why should it be any different if the businessman is a farmer.
As for phone calls, I would love to have the call screening that most businesses have these days:
Press 1 if you wish to make a payment
Press 2 if you are returning a call
Press 3 if you want to speak to someone-you are 67 in the queue, your call really matters to us, you are now 68 in the queue, your call.....
Press End call if you are selling something
