This was the first shop I took my mom too. She was nervous and kind of unsure, but luckily the employee we talked to was incredibly nice, explained everything well, and even "cheered her on". Additionally, we never felt pressured or ignored. I am very, very grateful to her for making my mother feel more comfortable and at ease without being judged.
The shop is a good size, not huge but enough space for lots of merchandise and standing room. The shop definitely has a more "edgy" feel to it, which I don't mind, but wasn't my mother's speed, so be aware if that's an issue.
My mom didn't want to deal with actual flower, so we only focused on vape pens and edibles. Their selection is good, but they don't have refrigerated stuff. They have a few different vape pen brands, which was nice. Their prices were also better than what I've seen elsewhere, which was a pleasant surprise.
All in all, 420 Carpenter is a great shop with awesome employees and good prices. I might not have chosen to take a nervous first timer there because of the atmosphere, but it was overall a really great experience.
