My advice
Nandos women go crazy for nandos
Premier inn you may spot Kenny Henry
Take some tunes lamb of god, trash talk, slayer
Surprise her take toys, lego not megablocks or you will look cheap
Buy a small bottle of grey goose vodka , then shitty shop brand once you have drunk enough of the goose refill the bottle she will be too drunk too notice and you will look classy
If your go were I think you are going don't go to the concourse head the other way towards Kingsbury there's a pub on the concourse but you will get mugged
If you stay in take a movie, a big weepy like schindlers list girls love a weepy and it heightens the mood
Finally if it goes to shit give me a call beers, fifa and I'll listen to you why you talk about your feelings £200 overnight
