What Does "Reasonable Offer" mean?

How much of my time is farkin "wasted" here trying to help as many people as I do? Talk about an absolute cop out. Wasting time my big old butt.
I don't care how you and others haggle, not saying you can't do it your way, my buddy is great at low balling, I'm not, I'm not trying to argue with you or piss you off but if the seller ask for reasonable and you low ball, the way I see it your purposely disrespecting the seller, aka being a dick, and yes their sometimes gonna get mad for people wasting their time. Do I care, No, unless I'm the seller lol.

I drove cab for 20 years, for some reason people think it's ok to haggle a price for every ride, and heard and dealt with all kinds of bullshit from customers.
