Depends on the industry. For very large transactions, like if you are paying a home improvement contractor for something, they will often make you eat the fees if you want to pay with a credit card. So you end up having to figure out where your checkbook is (probably collecting dust in a box somewhere).
I give Bitcoin and LN a continuous pass on UX for now. We're in the infrastructure phase -- growing trust and improving reliability matters far more than UX. Before you know it, there will be 20 years of development and battle-testing behind the tech. The UX can come at any point in the future, while a breach of trust would be fatal. It's a question of ruthless prioritization. Thankfully, the open source devs behind these projects are long-term thinkers, not ponzi-scheme enablers.
Lastly, the UX need not come from Bitcoin/LN. They are a protocol, not a product.
