Yes espresso drinker thank you for the advice. Unfortunately not all airports are the same and if (as I have done) I hold up the queue by taking everything off unnecessarily then the security despots and other pax get equally p*ssed off.
As far as fluids are concerned it is the same - no consistency. There are also airports where you can pass through security, then innocently buy some water for your flight at a kiosk near the gate and then discover another security check at the gate.
There are not many major or regional airports that I have not transited through. Don't get me started on checked baggage and carry on allowance differences either.
