No, and soda isn't tea anyway. Not sure what you're getting at.

You're thinking of magnets

That's actually more true than not. These soda shops are essentially an alternative to coffee shops for those who believe drinking coffee and tea are bad. It's the same caffeine fix, but without being coffee or tea.

Idk, I grew up in WA and saw them there, and I've seen them at gas stations along the way in Idaho, Oregon, and Washington (we drive back once/year).

The smaller gas stations don't seem to have them, but the larger ones do, especially those "oasis" stations. And we tend to stop at larger gas stations, so maybe that colors my perspective here.
