Uuuhhh... not dumb!

You see a variety of things. Rarely do you see anyone bring something to sit on. Just not enough room.

A lot of people do not sit on the ground to put on socks/shoes... they do it standing up. It saves time. Those are also people who probably have speed laces on their shoes and run without socks.

As for me, I stand up in T1, since I just dry/clean off my feet with a small hand towel and then I pop on my cycling shoes sans socks.

For T2, I typically end up with my butt on the ground while I put on socks and shoes.

Yes, my transition times are horribly long!
