Assuming it is an active real estate with lots of transactions, yes, the agent is absolutely more motivated to close the deal and move on to another deal than to get the highest commission possible on a particular deal. The situation is similar with recruiters. It is important to understand these motivations to correctly interpret what you are hearing from the agents/realtors.
I used to work as a waiter when I was in my first summer out of high school. The calculus was similar there. When it was busy the tables turned as soon as the person got up, so I would often not emphasize dessert. The added $15 on the check from dessert increased my tip a couple dollars, but regular desserts could cause me to lose 1-2 full turns of my section over the course of the evening, so with a four table section of everyone for dessert, I might lose 8 tables total, and if the average tip was $20, I’d lose $160 minus the extra $16 in tip gained from everyone having dessert. Point is, I much preferred quick turns over small per capita increases in per table tips.
In non rush times though where tables didn’t get filled when people left, it made a lot more sense to play up dessert.
