We have a used car dealership that is writing checks of off their business deposit account, made payable to their business, deposited back into the same business account. I'm confused and dizzy thinking about it. Does anyone think this is strange or can possibly share a legitimate reason why a business would do this?
TGIF!

don't speculate, ask the customer

He's artificially inflating his balances for the daytime, and whatever his purpose might be, it's not a legitimate one, not to mention creating a lot of commotion and volatility in his account and needless work for the branch. I would just tell the branch to put a stop to it, personally.

Ask him what he is doing. The tone of his response may be as important as the content..

Ask first. If it doesn't make sense (I doubt that it will), THEN tell the customer to stop it.
