My thinking is that the government has asked for these surveys to make sure the restaurants are switched over to the higher level of recycling. I did a few places that are now using mostly a thick paper or thin cardboard type of packaging. But other places I have done are still using the thicker black plastic containers. I am not sure what they are allowed. I look at photos on yelp for each place I do to get an idea but some of those photos are older and not what the place is using now.
Unfortunately I seem to be locked out and not allowed to get another job. Maybe tomorrow I will be allowed. There are still quite a few places available in my area.
