Was sitting in 21B on UA 991 from IAD to ORD this morning. After the beverage service, I watched two flight attendants spend about 40 minutes opening every can of unopened soda and juice, about four trays worth, and pour the contents down the drain in the mid-cabin galley in Economy. They also empied about a dozen full unopened bottles of water. Overheard one of the FAs speaking with another crewmember about union action.

Planning on providing this info to UA. Anyone else seeing this kind of action?
