Oi! Take your gel packets home with you!

Sadly I agree. I hate putting the sticky thing in my back pocket.

As long as you don't drop the sticky thing on the floor where some poor bugger has to clear up your mess.

Have you ever tried to put a used gel wrapper back in your pocket? It's fiddly and messy, you end up with sticky goo all over your hands and then the dregs seep through your jersey and make your back really uncomfortable. Much easier to just toss it.

Yes, it's really really easy to put back in your pocket without the gooey mess with a bit of practice. Perhaps try practicing first before being particularly selfish.
