The law supposes or assumes that a person will always pay for a thing
purchased
The law supposes or assumes that a person will always pay for a thing
purchased. If I should go into a store, inquire the price of a book,
and, after learning the price, should say to the salesman, ‘I will
take the book,’ and he should wrap it up and give it to me and I
should then walk out with the book under my arm, he doubtless would
come to me and say in his politest manner: ‘Why, sir, you have
forgotten to pay me for it.’ Suppose I should say: ‘Oh, yes; but I
will come in to-morrow and pay.’ But if I happened to be a stranger,
and especially if there was a suspicious look about me, and he should
say they did not give credit in that store, and I was still inclined
to walk out with my book, he could insist that there had been no sale
and that I must give the book to him. The law would protect him in
taking it from me if he did not use undue force. The law assumes,
unless some different rule exists, that the buyer will always pay for
the thing purchased, yet in law there is no sale unless the purchase
money is actually paid.
