Um, there’s a reason providers are often called “pros”. They do this professionally, as in it’s a paying job.
Im professional at my paying job; I expect the same from any profession.
I don’t personally like many of my clients. Their politics, mannerisms, bad choices, etc. But they are still clients and they deserve my best.
Ill never hire anyone for any job when they have some arbitrary standard of what clients they feel are beneath them.
