Spouse had a home-based collectible business for 28 years until one year ago and the phone # remains unchanged. I answer the phone on 99 percent of calls. Through me (or so they'd like it), three clients in particular badger him (age 76, getting more confused by the month) to "sell me just one more item, it's only one, and I'll pay highest price, aw come on now." They don't get by me because he's stated to them and to me that he's retired. I can't be home 100 percent of the time; he's resisting changing the phone #. Out of 11 phone calls on this topic last year, about 3 times he's given in to clients he's known for 20 years or more and regretted it.
They're avid collectors from all across the country; many know each other and pass along information among themselves, so they realize he's retired with still a large inventory. What is an effective way to tell them to buzz off? Appeals to their sense of appropriateness or kindness don't cut it with these bozos.
