Tonight I bought items from HyVee (local grocery store). The items totaled $16.37 and I handed her a $20 and 37 cents in change. The register female (college age) could not figure out how much change to give me. Really?? A week ago I tried to buy something at a convenience store for about $5 and gave the clerk a $10. She gave me change for a $20 and I had a hard time convincing her that she gave me too much change.
