At MAN in April, I forgot to take my 2 cans of energy drink out of my rollaboard.
The terminal was pretty deserted when I got there (understandable since it was lunchtime, the longhauls to Asia had departed, and my flight was leaving at 3ish), and there were 7 security personnel, and not one other passenger being screened.
Waved through without a word...Should have brought some liquid explosives instead... @:-)
