Politics aside, Petrochemicals made other valid points: you are on a small overpopulated island (even without the government, neighbors and others should be close by to help) There are few natural disasters which might disrupt normal routines for very long. I suspect his comment a roll of £5 notes being something to have was made a bit sarcastically but having cash is really good advise —- during power outages plastic cards won’t work.
Even if you believe in governmental aid and have an effective system for getting it, it still won’t be instantaneous or complete.
****Possible scenarios?
- Evacuate from your home due to flooding
****Likely immediate government responses?
- Set up shelters and feeding stations along with emergency care
Even with immediate shelter and food needs taken care of you still will need to have special meds (emergency shelters can’t predict all possible needs and keep that large a stock) ways to entertain your kids, care for your pets, and possibly specialty foods (my daughter’s a celiac and most mass supplies foods are things she can’t have)
Cash is universal, I keep 20 quid in my bag, a tenner of one's and a tenner of 50p's incase I need to get a bag of crisps from a sports hall vending machine, an exact fare bus journey, a shop not having any change..... whatever. I like to keep at least 50 quid in my wallet too. While on the subject of cash, I like to keep a good few hundred in the house for similar reasons, its handy having cash to fill the fuel tank or whatever, it sometimes gets raided to pay for takeaways too.
