Did Crosstown have a valid contract with Borman concerning the use of the crane? If so, was it a bilateral or a unilateral contract? Explain.

Grant Borman, who was engaged in a construction project, leased a crane from Allied Equipment and hired Crosstown Trucking Company to deliver the crane to the construction site. Crosstown, while the crane was in its possession and without permission from either Borman or Allied Equipment, used the crane to install a transformer for a utility company, which paid Crosstown for the job. Crosstown then delivered the crane to Borman’s construction site at the appointed time of delivery. When Allied Equipment learned of the unauthorized use of the crane by Crosstown, it sued Crosstown for damages, seeking to recover the rental value of Crosstown’s use of the crane. Using the information presented in the chapter, answer the above question.
