DW is ready to go out and eat at a couple of our favorite restaurants now. She doesn't want them to go out of business, and I don't blame her.
For the most part I am ready too. I am just not interested in dining in a restaurant where I feel like I am being attended to by a hospital cafeteria staff, or I need to be in some sort of air-lock to eat a meal (some exaggeration, but not by much).
Also, any requirement that I have to wear a mask inside a restaurant is a non-starter and rather pointless at that. Any fiddling of a mask inside the restaurant just to eat defeats the purpose of a mask. Heaven help me if I need to cough to clear my throat while eating.
So, I can't answer the poll question. If it were pre-COVID-19 conditions, immediately. For the requirement to get to 100% "safe", months from now.
