Would it make some of you happier to make cashiers use an abacus?
I can not remember when I had an issue at a retail establishment where correct change was a deal breaker.
I have more important things to fret over like parcel delivery and flip phones.
I don't believe young people in retail can make change w/o a computer to calculate it for them but it's not their fault, they were never taught how.
I'll take young folk doing it with a computer every day over octogenarians with a coin purse and an attitude when I'm in line. But I self check when available, to avoid just that, along with septuagenarians who don't start writing their check or even looking for their checkbook until the last object is bagged and the total shows on the display . . .
Edit: If you read this and think I'm referring specifically to you, I probably am . . .
If I were to go to a fast food store it would be Burger King. They have soft ice cream.
Even better is Wendy's the Crispy Hot Chicken Sandwich is the bomb. I don't think they have ice cream.
