In other words, we can trust the store's "store finder" to have reasonably accurate information about opening hours and which store locations are currently open for business. Any the additional imports copy over opening_hours type stuff, but leave the OSM geometry alone. If the chain lists a location as 'closed', that generates note to a local mapper. -- Armchair mapping of chain stores faces another problem: while some chains have iconic buildings, on occasion they sell out. Thus a mom & pop restaurant in a iHop shell, or an old style Taco Bell that's now a pizza joint.
