Actually, I've never seen a liquor store round these parts. ;) No really! I'm sure they exist, only we're more likely to call them poshified things like Rameses' Finest Grape Crushers and as such they've passed me by. Either that or they were banned by an Act of Parliament in 1837 out of fear they might corrupt the populace. One of those. ;)
Indeed you may reside in a wing of my mansion ;) but first I must provide you with the following pointers:
Barrels' Top Five Rules for Being All British and Such:
1. Gently steer every single conversation you will ever have round to the fact that the weather is completely sh*t today, isn't it?
2. Practice holding doors open for random members of the public. If said random members walk past without acknowledging the courtesy, chase after them with a bloody big stick and instil the virtues of politeness into them.
3. Respond to all uses of the phrase Harry Potter and the Sorcerer's Stone with snarling, foam-flecked rage and a visible vein in your forehead.
4. Cry every night when you're reminded exactly how stinking the UK selection for Netflix is.
5. Develop an utterly inexplicable but nevertheless unstoppable passion for After Eights, Poppets and Fry's Chocolate Cream.
THERE. ;) Now you are ready for your citizenship test HA LOL JK BECAUSE I FAILED MINE
