I've just realised who Susie is. She's Hyacinth Bucket from
Keeping Up Appearances!
When Nikki said Susie wouldn't drink wine because it only cost £10, that cinched it for me.
She's trying so hard to be seen as posh, and doing the things she thinks posh people do, but the truth is she's just a wannabe. Just like Hyacinth, she's desperate to impress, but can't hide her true colors at the end of the day.
Pity she's not as funny as Hyacinth.
