No I will not give it to a store or even to a charity a store tells me to give towards.
I will give it to a cashier and tell them to use it in case they are short or a customer is short. I will round up and tip restaurant workers with cash, I will give money at church and to people in need on the street.
Actually, I am rethinking tipping workers at the register and here is why. I just discovered that tips are treated as cash advances by my credit card so I am paying extra interest on that AND there is no way to clear that particular expense until the card is at zero for a while. Tough to figure out. I had a cash advance charge pop up on a card and I couldn't identify it and the credit card people couldn't identify it for a few months and it was stubborn because the card went to zero a day then I used it again and it still stayed there. It was plainly a small amount since the finance charges were only a few cents but stubbornly there month to month. They said it only comes from cash out and I could see the month it started and there was a pizza charge there and I remembered giving a tip on the card instead of cash. Credit card refunded the few cents. I made it zero again and left it at zero at least a week. It is easier to keep on carrying around cash, won't be doing that again.
I imagine the extra money to round up at stores is also a cash advance, be careful out there they get us at every angle:/
