Looking around at some of our major airports, the security staff generally give the air of:
1. Being the folks that McDonald's rejected,
2. Not being particularly good at their jobs,
3. Not being bright enough to work anywhere else,
4. Not being bright enough to realise they could get more money working as a security guard in a shop, or as a cleaner.
£6 per hour? The airport owners are getting ripped off. I rest my case.
(Your grammar and punctuation are terrible by the way. Security Guard? I take it you is one?)
