Two hundred a day for a well traffic area does not look like much profit, let alone that appears to be before taxes, fees, and other such expenses. This is for a business that would be very dependent of location but also weather. Have these been used inside of enclosed shopping centers/malls? Is the kiosk size cost many of those charge worthwhile to a business such as this? How about at airports? How are small setups like this treated by cities with regards how some do not seem to care for food trucks?
