This I do know how to do, as I have 1 everyday! After finishing the cup, squish the top together and with your thumb nails roll it up... much easier than the teeth. (p.s. in 2 years I've one 2 coffees & 1 donut!!)

So..
I go into Tim Horton's today to get a coffee and bagel.
I like Roll Up the Rim because it makes Tim Hortons more fun.

I'm just wondering how everbody else feels about people chewing on their cups in public!!

People don't normally chew on their cups... However, when it comes time for roll up the rim, they're a chewin'!

Is there a more graceful way to find out your roll up the rim to win fate?

Canadians, please advise me on these serious Tim Horton Etiquette matters. :)
