Paper for tossing chewing gum
Even though you’re allowed to chew gum in public, some areas forbid it. For instance, if one of the staff at a train station see you chewing gum while waiting for the train, they’ll politely inform you to toss your gum away before boarding. This is a rule we wish our department of transportation would implement.

When you purchase chewing gum, you’ll also get enough sheets to dispose of your gum after they’ve run out of sweetness. These small sheets will come in handy if you don’t run into a free tissue distributor and don’t want to touch your gum with your fingers.
