No one was questioning whether or not birth control is free...
Some people seemed clearly to be under the impression that, or wondering whether, not charging foreign visitors for birth control was an oversight or inefficiency. For example:
She was honest about being a visitor and being required to pay but the people she dealt with weren't aware or didn't care.
However, if overseas visitors are supposed to pay for contraception like they are supposed to do for any other non-emergency medicine/treatment, then I think it's annoying that the correct procedures weren't followed in this case.
It is my understanding that the NHS was not created to provide the world with free health care!
Which led to the query as to whether it could be charged for (i.e. whether the NHS was set up to accept fees).
The fact is, as we know see, that birth control is free for everybody.
The NHS is set up to bill for, and accept payment for, services and treatment where it is appropriate and cost effective. It is clearly a policy that charging a small minority of clients for routine birth control services is neither of these things.
