Hello @praditya. Thanks a lot for nominating me to participate in your post. Apologies as well for my late reply as I've just started to be back online after the huge devastation caused by super typhoon Rai (Odette).
Why not right? As the world is now slowly embracing the cryptocurrency phenomenon I believe other business models, especially in the hospitality sector, must show interest in its immediate adoptation. Not only does digital tokenization improve innovation due to its decentralized nature, but coffee shop owners would also find it more convenient to transact with customers faster and safer while saving paper. It's not a matter of how, yet it's a matter of when this amazing technology would be adopted globally.
