Orla engages Patrick to promote Orla's 'Sonic Drone' services, which provides high-end support to farmers to optimise agricultural operations, increase crop production, and monitor crop growth. The terms of the agency contract specify that Patrick may only give 30 days' credit to purchasers and will receive two per cent commission on all sales arranged by him. Patrick negotiates contracts with Liam and Shauna, and incurred considerable travelling and subsistence expenses in order to do so.

In his negotiations, Patrick represented himself as Orla's agent to Liam, but not to Shauna. In addition, Patrick agrees that Shauna will enjoy 40 days' credit. Contracts are entered into between Orla and Liam, and Patrick and Shauna.

Orla subsequently confirmed the latter contract directly with Shauna. Subsequently, a dispute arises between Patrick and Orla, and Orla refuses to supply 'Sonic Drone' services to Liam and Shauna. She also refuses to have any further dealings with Patrick.
