I'd suggest they put a couple of picnic tables out in the parking lot for take-out. Curious about other commercial operations that could satisfy the rule "... all gatherings under 50 participants are prohibited unless previously announced criteria for public health and social distancing are met"? Take-out biergarten? Silent disco?
Rules like this dont need to be enforced (or even enforceable) because by and large the community is onboard. Ie if Canlis, a Seattle institution ,was seen as looking for loopholes and risking lives it would be the end of their entire business.
I didn't mean to suggest anything nefarious. On the contrary, I'm curious as to what kinds of "fun" and "social" celebrations we can do these days while still limiting coronavirus risk.
