Pour one out for Andrew. They did many things that didn't scale that customers loved them for, and then couldn't scale. They burned lots of cash on outside sales, i.e., flying a rep from another city to visit a potential client small restaurant. And being a publicly-traded company is often more trouble than it's worth.
PS: I used to live in a van on the street near the PA HQ. Someone there had a tiny trailer in the parking lot but I couldn't tell if were living it or just storing it.
