Stop in for a cup of coffee

Local relator my friend knows just sold a house he owned. The buyer wanted to bring him cash for it a very upper six figure house. He took a quarter of the price cash and now doesn't know what to do with it. Can't put it in the bank he'll get reported. Trip to Vegas?? Spend it as cash?? Worried to having that much money in the house. Time for a BIG safe deposit box.
Problem with those are when you die.
An IRS agent will be stranding next to you when it gets opened.
Had that happen to me when my grandfather passed.
Funny though , he left a message and a penny in the box addressed to the IRS
Sorry this is all that's left
