How can cabin crew not know how to handle 50 lb overweight bags, or identify if this is beyond them, when they have been (presumably) trained to "assist" (manhandle) 200 lb adults onto and off the emergency slide ?
I do accept that there are a proportion of nuisance, "entitled" passengers, who will get a kick out of getting a 'flunky' to handle their bags. Which should be suppressed.
