Anyone who wanted to buy the round would have to come round with me and work hand in hand for a change over period, to get used to the way the customers like things done, be introduced, the system that I've been using to maximise my time and get the best results etc.
I have never had a customer even question trustworthiness, but then most of them don't have Ming vases, most household items are very low value and it's just not something that comes into question.
Besides I wouldn't just hand over the keys to a new owner without taking them round and have my customers unaware of what is going on, that would be ridiculous and foolish for any potential buyer, they wouldn't know where to start.
Besides there's a car, website, marketing strategy etc which would have to be explained.
