actually i was wondering that too. i find the inner silver foil is a bloody pain sometimes. but just stick with it, the more practise you give it the better you will become.

I also find helpful, that if you slide the tube out of the paper wrapper whilst submerged still in the foil, and then open the foil. then wrap the polos back up and slide the tube back down the paper it lessens the difficulty encountered later.
of course you must take care not to let the polos all escape all over the floor whilst you take the foil apart, and also be careful not to damage the wrapper when sliding it back in.

of course, you may think there is little point sliding the tube back into the wrapper, but i think it gives a sense of achievement knowing you are eating polos from a packet in its entire wrapper, rather than a flimsy bit of foil.

if you are having problems with the outer wrapper, this is a problem. it is quite easy to tear as it is made of less dense stuff than the foil, just take your thumb and forefinger and rip a little tear at the top just enough to get the desired amount of polos out, and then continue like this until the packet has been digested.

Dont forget to put your empty polo wrapper into a bin when you have finished, and make sure you have 27p for your next packet.

Practise makes perfect and i think once you got the hang of it, you will never fear buying polos again.

hope this helps.
