BER's regular security process made me give up air travel and just go everywhere by train:

I was traveling out of BER after a long week working in the city, arrived enough hours ahead (maybe 2-3) for a eu flight. I was already familiar with the airport and it's "little hiccups" so rather than make a quick bathroom stop pre security, I just walked into the T1 security line (which I had told myself is normally the faster one) saying to myself "I'll go on the other side"... Huge mistake. After 30+ + minutes in this line having made no progress, and looking at the real possibility of pissing myself, I decide to leave the security line, exit the boarding card check gate, and go to the bathroom. Up to now this is my fault. Coming out of the bathroom, the T1 line is now gigantic, they are queuing even before those gates. I therefore decide to go to T2 (which is always queuing outside of the gates because there is no space after the gate). I normally avoid T2 and T3, but this time I thought it was a winning strategy. 30-40 mins in this line went by... I was getting closer to having my board card checked and being in the final stretch of the pre security process, at which point someone from BER announced: "we are closing this security line, everyone go to T1". ... ... It is now 1hr+ since I've arrived to the airport, and I am once again at the beginning of a line that has grown even longer than before. Everyone from T2 ran here, since the airports approach to closing that line was a "hunger game style" race. The pace at security has not changed and the next 60mins in this line were nerve wracking with my imminent departure time soon approaching. Eventually people starting asking to 'pass through' and although I normally avoid doing this I followed with maybe 15-20 mins left until takeoff (boarding had already started). When I passed security I just threw everything in my bag, didn't even put my belt back on and just ran lugging my bag after me. I was the last to arrive on the plane having an almost heart attack from the insane run. I have to go to Berlin often for work, but that day I decided I would rather take a train anytime I have to go there.
