disloyalty fee
n.— «Use that bank machine that’s not from your own bank and you’re undoubtedly going to see an immediate service fee plus your own bank dings you another $1.50. That’s what’s known as a disloyalty fee and the banks say it’s justified as they rake in record-breaking profits like the CIBC for example, which reported profits of $2.6 billion for the year.» —“Canadian ATM’s offer quick cash at steep cost” by Jaime Pulfer 680 News (Toronto, Ontario) Dec. 8, 2006.
