Can I earn rewards retroactively? I just went for the first time, but was unaware of the rewards program until after the fact. I would still like to earn points on my purchase if possible, as I will be frequenting this location.

Yes

That's weird they didn't tell you about it, the bud tender I got the first time I went new I was a first time customer because the woman up front that checks you in puts it in the system. Or so I thought 🤔

No. you can from here on out.

Not sure about the rewards... But did you get a free 1/8 for your 1st visit¿?
