Be careful of that bullshit. You just stepped in it.
Google has this to say.
If you turn down a full-price offer, you may still have to pay your agent, depending on the contract.
“depending on the contract.”
LOL, sure sport. No sparky, even if a full price offer comes in, you do not, even if your vaunted google says so. Depending on the contract... lots of daylight there.
