Your friend has got some good experience and lucky to use bitcoins in KFC in Canada and well there is nothing fancy in this because they
have to introduce something new to their customer in order to get some good results in their business or services. Even Mcdonalds are trying to introduce bitcoin and apart from these companies, i am also connected to many local shops here in my city Pune, who are using bitcoins for transactions and i recommend them to share these things with your regular customers too.
