Public speaking isn't easy ¯\_(ツ)_/¯ I think I would briefly explain the concept for the benefit of anyone unfamiliar, and I would remove the "I guess" part from the front. My area didn't have an Aldi's until...idk. I want to say 2009. So it's old enough news to me, but maybe there's some people that have a Kroger/Walmart/everything else.
