Sorry, Lizzie — some of my comments on your intelligence were unworthy & I do wish I hadn't said them.

Your above job description sounds a delight, & the practice were very lucky to get an employee as dedicated as you and you were lucky to get employers like them. But I don't exactly see its relevance to the topic of this thread. All one can say is that it would be nice if everyone were so loving and appreciative.

Unhappily, it isn't so. You know that there are, e.g., thieves, who will steal from their employers if they can, & from whom employers have not only the right but the duty (as Ruth A pointed out, in the interests of the honest majority) to protect themselves by any reasonable and honest means at their disposal.

Honestly now, Lizzie; starting again with a bit of goodwill between us, please; and bringing that intelligence of yours to the question — how can you fault what I have just said?
