Most banks do not check for counterfeit's either. They don't want to be holding the bag (they would be obligated to turn it in, no compensation). Another dirty little secret of our banking system.It came from the bank so I assume it's real. Wife wanted to cash last weeks paycheck vs me depositing it.... She does weird stuff and does not trust banks in today's world.
Retailers not taking cash are just being lazy - they don't want to handle it. I won't shed a tear when they go under. Maybe they could invest in one of these.
