Secondly how and where are people supposed to get diagnosis and prescription for a Uti if you can't see a doctor?
For many patients simple UTIs are now diagnosed and treated over the phone by GPs, you often don't need to provide a urine sample as you can be diagnosed based on symptoms. Or in some practices the nurse can diagnose and prescribe for UTI.
Due to the nationwide GP shortage, many practices are employing other professionals to do jobs previously done by GPs, eg nurses, pharmacists, paramedics, physicians assistants, health care assistants. Patients will often just ask for a GP appt as they won't know that the pharmacist now does virtually all the medication reviews, the nurse practitioner sees most on the day urgent appts and the paramedic does most home visits. Although some patients do prefer to see a GP, in some practices GP appts are a very very limited commodity and they try to reserve them for patients who need to see the GP. Many patients however are happy to see the alternative professional when suggested by reception but they wouldn't know to ask for them.
As a GP it's fairly common for patients to book an appt with me for something I can't actually do, or which requires a special type of appt eg a longer appt, although our Receptionists do ask for the reason at booking. Then they are irritated when I explain they will need to come back and see someone else.
