Your Country is Not So Bad If There Are Tools to “Roll Up the Rim”
In Canada, the coffee shop franchise Tim Hortons (the possessive apostrophe on Hortons was dropped by the company) has an annual contest in which anyone with their paper coffee cups can “Roll Up the Rim” of it to see if they win free coffees and much more.
It’s not my bag and I’ve never done it.
But most Canadians have embedded this successful marketing program into the very fabric of Canadian national identity, never mind the fact that the company is in fact… err… American owned.
But no way would taking those 10-15 seconds to manually reveal the prize or “Sorry Try Again” be acceptable. Canada is a great country because entrepreneurs have come up with key chain gadgets to make it even easier to “Roll Up the Rim.”
If your country is not in a position to have frivolous contests at coffee and doughnut shops, with accessories, it’s not great as Canada. Either that or your country is not so lazy.

In other words, it replaces your mouth. I use my teeth to unravel it. People do it real hard and get a really bad pain in the mouth, trick is to be real patient. Not really in a huge rush for a free donut.
Ah, so these devices are so we don’t get a sore mouth. They are safety devices!
Maybe, though there are much easier ways without cost.
