"See if you last a day without being rude to a patient" NEVER ANY EXCUSE for this if you can't manage it leave the job!
As a nurse I've been shouted at, sworn at, spat/vomited/peed/poohed on, pushed, grabbed, cornered, still wasn't rude to patient!
In terms of patients being frustrated at lack of appointments - that's part of your job to deal with that and feed back that frustration to the gps. ANYONE working in a customer facing roles has to deal with irate customers. You're representing the business (and GP surgeries ARE a business). Don't like it? Leave the job!
"I couldn't care less about what your problem is" seriously leave. The. Job
"Sometimes I wonder why I still stay at this job" so don't.
"all things that would waste an appointment" in your NOT MEDICALLY TRAINED opinion
"It's also shocking how many patients come in 2-3-4 times a week to see their doctor, just to chat" and now you're looking down your nose at the lonely/mentally ill! Delightful! Btw the mentally ill (of which I am one ALSO DESERVE CARE)
PLEASE don't do this job any more you're clearly unsuited to it.
Here - massive problems with confidentiality (county wide, numerous reports, currently under investigation with lots of retraining taking place).
Only 1 'ailment' per appointment THAT ridiculous rule is why my dds disability went undiagnosed for years.
