Mass adoption probably won't happen in a way we're expecting it to happen in. I don't think that it will a regular thing to pay for your coffee or dinner using BTC. It may become a way of paying for something online, but I do see it more as a backbone technology and asset of some sort (yet to be determined).
It's probably going to take a lot of marketing work to get it out there for the common pleb. Probably some celebrity using it and tweeting about it would make it really known amongst the non geek herd.
I don't think that people can be influenced that easily. There needs to be an incentive to use it. Marketing doesn't work how many people think it works. If it was enough to have some rich celebrities advertising your product, the Tidal music service wouldn't fail like it apparently does.
The Tidal comparative is a good one. However, some good ol marketing never hurts.
The great thing on Bitcoin is accepting payments as an entepreneur.. just look at this:

It's very interesting to see which people opt to use Bitcoin. Many if them even had a bad encounter with banks at some point, while others simply admire the idea and technological possibilities behind Bitcoin. The example you're talking about is an interesting one! But I'd also like to see more instances with "regular" businesses so people see that you don't need to be someone "crazy" in irder to accept Bitcoin!
