I assume Wikipedia is never wrong about anything, so they can't be wrong about the origin of the name "Nickelback."
There's such hype about the pride Chad and the band members have in the band, and how deep the lyrics are, and how awesome at life their fans are, but, did you ever stop and ask yourself, "Why, self, do I think they chose the name 'Nickelback' for such an incredibly awesome [at sucking] rock band?"
The answer lies with Starbucks. That's right, Starbucks. The frilled-up coffee place.
Turns out Mike Kroeger used to work at Starbucks serving what were no doubt some of the deepest, most thoughtful lattes this side of France. (Mike, by the way, for those of you who have too much of a life to care about these things, is the half brother of Chad Kroeger and bass player for this talented menagerie.) While working at Starbucks, Mike found that he would often have to provide the customer with 5 Canadian cents in change. 5 Canadian cents, when placed into one coin, is also called a nickel. (Similar to the US but at 70% of the value.) Apparently, during this transaction, he would frequently find himself saying "Here's your nickel back."
Long story short: Mike served crappy, over-priced coffee, gave people nickels, formed a crappy band and should now technically owe Starbucks all sorts of royalties. Thank God he didn't have to give people some sort of other change back or ever say anything else to any customers on a routine basis, like "Here's your penny back," or "Here's your receipt ma'am." Those would have been horrible band names.
