Much as I will be the first one eating in a restaurant (never there longer than 10 minutes, maybe fewer than 5 with no mask), I do think there will be more outbreaks. We have had many clusters linked to restaurants.
A better solution (that would never have happened) would have been to have spaces opened up for people like cleaners and construction workers- since the pandemic, I have seen places TAKE AWAY public seating, I guess to discourage helpers from congregating on their day off. But that would have taken serious planning, something this government is not up to doing. I mean, hell, the schools are closed, they could have cranked up the AC and let people eat there...but this is not a government with an ounce of original, creative thinking.
So, yes, there will be more outbreaks...they should limit time spent in a seat to 10-15 minutes- eat and open up for the next person, no playing on your phone for the next hour. Restaurants need higher turnover of tables to make a buck with 50 percent of tables shut down...
