Would you negotiate buyer’s agent commission as the seller?

My house is for sale and I am paying my listing agent 3%. He’s done a great job and actively has spent a lot of time marketing and getting the property out there.

We received an offer for full asking price, and they requested 2.4% for the buyers agent. The kicker is, this offer came a day after an open house. The people who submitted the offer attended the open house. So their realtor hasn’t even spent time with them coming to this property.

Is it worth the like 2-3k to counter the buyer’s agent commission to 1.5%? It’s a good offer other than commission for their agent. Would you haggle over the few grand or just let it be?
