I was left, you know, very upset, very embarrassed, very humiliated,” Watson said
What was he trying to do to the agent?
without taking sides I am not sure what he thought would happen if he tweeted the experience. Anyone who posts stuff on social media should expect feedback positive or negative so he should only blame himself. If he had a legitimate beef with the agent he should have contacted WN through the proper channels and not aired his laundry in public.
