This is absolutely true. Only the tourists do not know. This is the same for rickshaws in HongKong, by the way. Some tourists think that one can actually ask some old guy to pull them in a rickshaw....but.... Actually, of course, the rickshaws that you might have seen, but probably not now, in HK and Macao were for photo-ops only, at a price. The old guys with rickshaws probably could not even move them an inch, if they tried. Most of the old guys look like they might need to be pushed in wheelchairs, themselves. These days are GONE.....
