Stopped by the local C-store to get a newspaper, and another customer asked if he could buy some coins. The clerk said they might be able to sell some, and the guy said "Great - I'd like $25 in toonies
. I replied "Nobody
can sell you $25 worth of toonies".
I guess this would also fall under "Sucky Customers" - wanting to get a buck's worth of your change as quarters for the laundromat is one thing, but don't expect a convenience store to be a bank - they need the change for normal transactions.
