Special Green Light

When I entered a department store I go to often, the sign under this green light caught my eye. The sign said "Push for Assistance" in Japanese and in English. There was a big red button below the sign. At first I thought it was for customers who needed help with items, but then I saw the rest of the display. It was for people in wheelchairs. See the picture below.




There were stacks of trays and baskets. The tray could be strapped around a person's waist to hold the shopping basket in place. The service was provided by the 7-Eleven Corporation that also owned the department store.
