Dude, Wells Fargo, Come On, Bro

I am not meaning to make a complaint or anything; I'd just like to point a pretty obvious flaw in one of Wells Fargo's processes. I used to use my WF credit card that came with the account, but since I switched primarily to Schwab (which has been phenomenal) a few months ago. I paid the final balance, and since you have to round to the nearest dollar for some reason when paying the balance by way of account transfer (aka. transfer from checking to the credit card to pay it), I was left with a negative balance of $0.66.

I didn't really think much of it until I got this in the mail a few weeks ago:

That's right, a check for 66 cents. So, instead of just transferring 66 cents back into my checking account, you (Wells Fargo) spent the money to mail out a paper check. Absolute best case scenario they broke even on that transaction.

Or, better yet, how about allowing me to transfer the exact dollar amount like literally every other single bank/financial institution does. I would imagine it is some kind of ridiculous banking regulation thing, and it's not as simple as I'm laying it out, but still.

And yes, I cashed it. In fact, I deposited it into my Wells Fargo checking.
