I agree with MagicCity.
Chances are that customer went home and the $90,000 ended up under the mattress or a closet safe. I'm not that concerned because of the length of time between these two transactions - 16 days. Chances are he/she is "unintentionally" structuring. He/she is probably slowly trickling the money back into the bank. Those fears might still be there, so putting the full $90,000 back right now, is probably out of the question.
I'd definitely wait until the 3rd one.
