Sometimes, when people have lots of debts elsewhere or are simply leaving the country, they just max out all their cards and never pay back. To the banks, because of how big the loss it would be, it's the opposite of "guilty until proven". I'm not saying what OP suggested would definitely lead to shutdowns, but it's always a possibility, especially when your usual spending is nowhere near that amount.
Did your friend tell them in advance he would be making large charges? We have had major home renovations the past couple of years, almost maxing out several cards, and there has never been a problem. Our credit score dipped....for a very short time...which I thought was ridiculous...why not wait to see if the customer does NOT pay in full? also several years ago we paid cash for our car, again almost maxing out our cards (and paying it off right away) and there was no problem.
They know your income, your assets, how long you've been a good risk...there has to be something more when you are shut down
just for making large purchases.
