We have seen a few videos showing strollers and kids messing around, but they don't always share the videos, and we have seen some where you really can't tell what happened. They did make a point to say that they didn't have these issues with the last service company. Our thought on that was that the last service company probably had it set incorrectly or never checked it. Funny story on that... our guys were doing clean downs on the escalators not too long after we took over service. They had steps out during the cleaning, and the mall management came by and said they had never seen that before. Go figure.
