The wailing guest is probably the only wedding commonality that irritates everyone else (save the offending party). The cash bar makes the groom's parents happy (it's less expensive), some will find the kids in the wedding party cute no matter what they do, etc.; however, this public nuisance is inexcusable and unforgivable. As another comment noted, a wedding should be about the bride and groom, not some attention starved aunt two times removed. (Of course these women are probably the most upset over the cash bar later on, at which time they don't cry alone.)
