Can delivery people make change?

Im ordering chinese food and it cost about $10, but i only have a 20. Can the person who delivers the food to my house make change?



Because I once gave too much, and they thought it was a tip, and the delivery person couldn't make change. I am just wondering if that was a one time thing, or if you need exact change when you order delivery food.Can delivery people make change?
Yes they should be able to make change for a 20. And if you don't want them to accidentally think you're tipping them 10 dollars, then before you give it to them, say, "Can you make change for a 20?" just so they know. It's a nice subtle way of letting them know and not being rude.Can delivery people make change?
They should definitely be able to change a $20. If you want to be absolutely sure then tell them when you place the order.Can delivery people make change?
