this seems like a really petty thing to complain about. The integration has not been easy for anyone, and I do not begrudge United/Continental employees a chance to let off steam in a harmless and humorous manner. It might even be good for morale. If seeing an ex-con bracelet on a flight attendant is the worst thing that happened on your flight, you must have had a wonderful trip. Save the bellyaching for real problems, like long hold times, reservations that don't ticket, lost legs and seat assignments, and irrops chaos.
