Perhaps a beer is implied (especially coming from the Heineklands).
Depending where you're from, you may need something like an ESTA only which isn't that big of a deal (similar to the stuff you need to go through in Canada). As far as customs - my personal experience is a mixed bag in YVR. No issues on that land boarder, but I could probably pull of a MAGA hat so there's that (hadn't had a secondary screening since '16, which is nice).
