fine, but let's not compare meal cost to a house. that 6% is very arbitrary. i never got how selling a home in a major metropolitan area would require 10 times as much work for a realtor than a house in the middle of nowhere midwest for 200k. the flat percent doesn't make sense.
The same argument goes for buying steak versus buying a chicken meal. The costs are wildly different but the work is the same, why should I pay the waitress more for one versus the other?
well maybe you personally shouldn't? like i said, not fair to compare a $20 meal where you're probably not going to die on a hill over 50 cents of perceived labor vs. a $1M house. You're also free to buck societal conventions and tip nothing and "only" be seen as an asshole, you can't do that with realtors.
