They are SO fucking annoying! I don't want some cap in my face while I drink, and I don't want to have to rip them off every time, leaving a potentially sharp piece of plastic I have to be careful to not jam in my face.

And where is the point in that? Here in Germany, all plastic bottles are returned WITH cap to get your deposit back. Who takes off the cap and then throws it away, to, you know, have a bottle you can't close? Escaped mental patients?

How about implementing it ONLY in countries where people - for whatever insane reason - throw those caps away on a regular basis?
