I have had 2 experiences of termination and both were very different, and I was very young and naive (stupid), so had no idea why they were so different at the time.
The 1st time I went to the family planning clinic and was referred to my local NHS hospital for the procedure within a few days.
The second time I went to my GP who said I had to go to a clinic 20 miles away, where I had to pay for the privilege of being talked to like an idiot and having a blood test. Only to be sent a week later to another clinic 40 miles away for the procedure where they were at least a bit nicer, but it cost me hundreds.
It turns out the first clinic's purpose was to talk me out of it.
The GP could have easily sent me to the local NHS hospital and chose not to.
I challenged her on this later and she said she had no idea that was what happened at that 1st clinic, she said she thought that the procedure was carried out there. 
Hopefully nothing like this goes on any more, but it made a huge difference to me; I was left with debt, I had great difficulty travelling. (am always extremely sick when pregnant, not great for train travel)
I also wanted to keep my situation private, very hard in a shared house when you are throwing up all the time, the extra week certainly did not help this. Not to mention the psychological aspect of the thing.
When someone has made the decision, it's not fair to make them wait, it's cruel. I don't think anyone does it lightly, yes counsel them to ensure they have not been pressured into it or something and of course talk to them about contraception and taking care of themselves. But lecturing them about the alternatives and doing this in a separate venue, causing more inconvenience and delay is not helping anyone.
