I brought a big, 3-mil plastic bag to one Starbucks that puts out grounds in 5-pound bags when they get around to it.
They were happy to dump their whole wastebasket full of grounds into my bag so they didn't have to shovel them out and bag and tape them.
I left quickly so other gardeners wouldn't see me hogging all their grounds.
7-11 seems to throw their grounds away before I wake up!
