The US absolutely has that combo at plenty of private businesses. I was in NYC last weekend and both Broadway shows required masks and proof of vax to attend. About half of the restaurants we visited also were checking vaccine cards and asking patrons to wear masks if they got up from their tables.

In Portland, it's much the same. Grocery stores are no longer mandating it but many restaurants still are. Concert venues seem about 50/50 at this point. There may no longer be blanket mandates but I'm still showing my proof of vaccine or being asked to wear a mask a couple times a week.
