I just don't understand the mentality of a business saying "we don't want to talk to our customers".
Nothing will help long wait times when there is an unplanned widespread outage, except perhaps a mass text campaign to message everyone affected to tell them you know and are working on it -
Seems like this could be done easily, even easier with email.
Here is a suggestion for you.
Teach about the Haka, what it means, when it's performed and why, how it came to being, what cultural significance it has etc.
Then ask your students to come up with something similar for their culture.
I think this would be a very neat way for the students to express their creativity and learn about and appreciate their own culture instead of mimicking another one.
