Israeli border crossings are the worst in the world for the traveller. Everyone is made to feel they are a suspect. London is strict but the security personnel smile and are apologetic for any delays. I found the same in the US - strict security but pleasant staff.Good manners and politeness do not rate very highly on the Israeli agenda. By contrast I travel via Jordan and the difference is 100%. Even regular travellers to Israel complain about the way they are treated.
