|At the only McDonald's in Rongcheng, Jieyang, China|
It looks like there may have once been a bottom step which matched the others. Perhaps McDonald's had extended the steps too far according to watchful eyes and paid the price, though it would seem to be a minor transgression in Jieyang where sidewalk space is often obstructed or nonexistent. Whatever the case, the narrower and probably less-stable brick step may do more harm than good.
At least they have another entrance to use.
