A grocery store in Canada is trying to shame its customers into not using plastic bags by handing out ones with embarrassing phrases like “wart ointment” on them — but the store reportedly found people still want the bags.

The East West Market in Vancouver announced the campaign in a video posted to their Instagram account last week.

The plastic bags available at the store are now emblazoned with slogans such as: “The Colon Care Co-Op,” “Dr. Toew’s Wart Ointment Wholesale” and “Into the Weird Adult Video Emporium,” according to the video.

“We redesigned our bags to stop people from taking them,” the store’s video says. “Avoid the shame. Bring a reusable bag.”

The shop’s owner, David Lee Kwen, told the Guardian he wanted to push people to help the environment with a little bit of humor.

“We wanted to give them something humorous, but also something that made them think at the same time,” he told the newspaper. “

Unfortunately, the bags have become popular with customers who are now taking them because they are so funny.

“Some of the customers want to collect them because they love the idea of it,” Kwen told the Guardian.

Still, the owner thinks his plan is a good idea. “Even if you have the bag, you have to explain its origin to your friends. And then, we’ve started a conversation,” he said.
