> I open my laptop bag as if I am searching for something
Don't make anyone think you have anything of value on you!
Also don't carry a light, easy to steal bag. The laptop goes into your suitcase.
As part of my routine when arriving at a hotel I study the fire exit map, maybe use the local vending machine, paying with coins from my pocket - gives me time to have the elevator all to myself.
I used to carry an emergency high-value banknote in my back pocket so that in case the worst happened I would at least have some money on me. The thieves that robbed me in the past never wasted time on full checkups.
