Beck was the general manager of chilkoot lumber co. haines sold fuel to the company. to persuade haines to sell on credit, beck signed a paper by which he promised to pay any debt the lumber company owed haines. he signed this paper with his name followed by "general manager." haines later sued beck on this promise, and beck raised the defense that the addition of "general manager" showed that beck, who was signing on behalf of chilkoot, was not personally liable and did not intend to be bound by the paper. was beck liable on the paper?
