The point was that there are a number of recognizable brands that have fewer stores than pandas in existance.
If you do want by to go by 'sales volume', it looks like the cost to rent a panda is about $1M/yr, for a total of 2.5B/yr. So you drop down to about position 43 if you want to sort by that metric. Still bigger than Midas, Jiffy-Lube, Baskin-Robbins.
We're pretty deeply in the apples vs oranges comparison at this point though...
