You still sometimes get transactions and fees within seconds of each other you - i.e. I had an ATM charge me the amount of cash withdrawn once and then the fee as a separate transaction. I get that you want to stop identical transactions within 5 minutes of each other, but I have a feeling there may already be stopgaps in place for something that simple.
