As many of the posts have gone away from the direct request of the OP towards closing that just had surprises, my first closing had surprise boobs!
I was reading through and signing documents, looked up, and was confronted with a nipple. The seller had raised her shirt and taken one out. Moments later she started feeding her baby, so it was completely appropriate, it just caught me off guard, as a bare breast was very low down on the list of things I expected to run into at closing.
(To be clear, breast feeding is appropriate in almost any setting, and I’m glad she felt comfortable breast feeding around a conference table with 6 strangers. To the best of my knowledge I didn’t do anything to make her feel embarrassed, and I would have been offended if any of the other people had suggested what she was doing was inappropriate.)
The purchase I had which fell through never got to closing. After the inspection we ran away as quickly as we could. That inspection was probably the best $250 I’ve ever spent. The owners even came back with a 10% price reduction, but that wasn’t nearly enough to change our minds.
