I'll take the TSA service at EWR, IAH or JFK over any UK airport. I can also only compare the queueing to be re-screened whilst still airside at T5 before being admitted to the shopping mall, sorry departure lounge, from my connecting flight to that of animals penned and corralled at a slaughterhouse waiting to be stunned before slaughter.
Couldn't agree more, T5 airside re-screening is an embarrassment! My most recent experience of this a few weeks ago was arriving from Seattle where the whole TSA process was calm, efficient and generally good humoured to be penned and herded through T5 by the most miserable people I had encountered since leaving the UK some 10 days previously....
