Does a store need to bag 1 can of beer?

* Generally, a single can of beer doesn't require a bag. Stores may offer bags for convenience, but it's not usually mandatory.

* Some stores have policies that require all items, regardless of size, to be bagged. Check with the specific store for their policies.

* Local regulations might require certain items to be bagged for safety or environmental reasons. Again, check with your local authorities or the store for specific requirements.

Ultimately, whether or not you need a bag for a single can of beer depends on the store's policy and local regulations.
