I've seen similar discards in many places around here too, Terri. And many are hesitant to do the normal "good citizen" clean up when out walking or hiking in order to deposit those into the trash cans.
Thanks, Nick. I've eaten outdoors just once at a local restaurant at 9 pm when no one else was around. This block of King Street, between Union and Lee, has been closed to vehicular traffic so that restaurants can offer outdoor seating on the sidewalk during the pandemic.
