I mostly have my pump in my jeanspocket, or clipped onto belt or bra... Only get the occasional doorknob if i have forgotten to hide the tubing under my clothes properly
Personally i don't even see a reason to wear a big bump that can't be disconnected

If someone wants to be able to manage bolusing without fiddling with the pump, there IS pumps with remote control

And the tubing... well, wouldn't it be worse to wear a big bump that bumps into everything

at least the tubing can be hidden under the clothes, it's even possible to use sticky tape and tape it onto your body as much as possible- only leaving enough tubing to be able to look at, and handle the pump...
Guess i just don't get it
