walking, as one has to do for miles and miles these days, as well as waiting in lines at least 4 times (checkin, passport control, security AND boarding) in Dublin airport, i passed many, many, many white courtesy telephones
I was terribly tempted to pick one up and just say "good day to you kind sir" as a courtesy, but for some strange reason, i refrained.
meanwhile, why are there 4 lines? why can't they do all the checks in one line?
why not have the crew at the security line, check the ticket, bags, passport/photoid,
what is their problem? are the stupid or something?
