Meh, I tilt all the time. At metal detectors, at the poker table, at windmills...
Seriously, I tilt through the WTMD everytime, to avoid brushing the sides. Nobody ever says anything. Anyone ever says anything? I'll go back and do it again (walk through tilted, I mean

).
Given the irrationality, inconsistency and general ill temperment of many of the TSOs I've encountered, if I worried about what was going to make them "upset", I'd have to avoid the airport altogether. Our mere existence makes some of them upset.
