Had my booster about 4 weeks ago.
Tip for those who are using the web site to book an appointment. If you search on appointments near you, and get offered something miles or weeks away, try searching on drop in centres. Some of them offer appointments too, but they are only listed as drop ins & don't show on the other list.
If you book using 119 you have to tell the call handler this too, as they don't know it.
I think it's a "thing" with GAWTs. I had one here that tried to bulldoze his way through the cat net I had on the french doors, and got tangled up in it. The next year I replaced the net with 5ft high chicken wire, so he jumped over that. I now employ both at the same time if I want the french doors open in summer!
