 Don't try to buy anything with a debit or credit card. And if all that's giving you a headache, don't bother going to the doctor either, maybe. I'm saying that because here in the UK, a lot of doctors say their computer system's on the blink, so they can't make appointments, they can't access patients' health records. And the latest is that some pharmacies aren't able to function, so you won't be able to get hold of an aspirin either.
