The Quiznos on 23rd street had a hand-written sign which read: "Restroom for customer only. No exception pls. Public restroom cross the street." Whoever wrote the sign had used the back of a weekly report for New York City, which showed the net profits for all 15 Quiznos stores in Manhattan. The stores were also ranked. The most profitable Quiznos was at W. 34th street. The Quiznos where I had just eaten was ranked 12th out of 15, which only cemented my opinion that the sandwich I'd eaten was below average.
It also had a "Q-Way" rating of 74.0, which was by far the lowest of the group. The other 14 restaurants all had "Q-Way" ratings in the 80s or 90s.
