How is the trend? I imagine it’s already possible to estimate what year it will be almost zero from that trend. It also tends to accelerate: once a restaurant has very few cash customers they tend to become no-cash because the cost of cash handling is more than the potential loss of business. I’m unsure if there are any legal obstacles to going cashless in the US however. But where I live no one uses cash and more and more places are cash free (a chicken and egg problem).
