I have been through customs in MCO, SFB, HOU and EWR and at all times i thought it was very pleasant. In every airport all staff were very friendly and sometimes a sense of Humour was shown. Made for a pleasant beginning and end to my trips. I have heard of people complaining about customs but I can say I have never had a bad experience when entering or exiting the USA
Thumbs up to all the TSA and Customs officials and staff at the above airports
