What a bunch of crap.
A few years ago (not sure if oscar was in town or Jeff at the wheel) a shuttle FA DID EXACTLY WHAT HER FA MANUAL SAID to do about serving soda inbounded to D.C. 
The anti, anti-Muslim uproar caused a social media backlash, and the poor FA was "fired" back to only doing delta flights, because, well regionals.
I've lost count of how many FA's have asked me to lift there bags, because their osteoporosis was flairing up, or the pregnant ones who still work in 2nd trimester, or I assume because her belly is well beyond showing.
We don't have the best looking flight attendants, good grief.   Heaven forbid we accept that we have thousands of grandmothers flying overhead right now.  I bet at least one or two can lift here own bags though.
