Didn't take long for someone to come up with a negative did it. Howver not sure what immergration is.
However reading the article 'all respondents were then asked ‘Baggage carousels aside, what do you consider to be the most time consuming aspect of the airport experience in the UK?’ to which the majority of respondents, 33 per cent, stated ‘security/customs’. As well as this, respondents also considered ‘check in’ (27 per cent) and ‘boarding’ (21 per cent) to be some of the most time consuming aspects of travelling via an airport.' No mention of immigration although I guess Joe public may refer to that as customs.
