Media types often like to portray Millennials as irresponsible and irrepressible narcissists who are more interested in squandering their paychecks on pricey avocado toast or on ill-fated music festivals held at private Caribbean islands than saving for the unforeseeable future.

Many of us will head to the grocery store this Memorial Day weekend to pick up a few items and, inevitably, that includes grabbing beer, wine or a spirit product. We have our list in hand and a pretty good idea of what we're going to buy. But something happens to 21% of us while in the store: We change our mind.

You've heard the stereotypes. Those youngsters are glued to their phones and don't appreciate the simple idea of walking into a brick-and-mortar shop. After all, they could just type a few keystrokes and have whatever they want delivered from myriad online retailers. And this is all reinforced by many retailers reporting declining sales year over year. So isn't it curious when you hear reports that millennials actually prefer shopping in-store?

A few years ago, brands like IHOP got caught using millennial-friendly lingo in their social media post. Some wag founded a Twitter feed called "Brands Saying Bae" that preserved their efforts for future generations.

Mobile marketers, take note: Millennials already live in an omnichannel shopping mindset. In fact, they were living in this mindset years before most businesses realized they needed to adjust operating models accordingly. These young shoppers carry with them the central expectation that a spectrum of seamless and consistent online and offline engagements will be the norm across their shopping journey.

As marketers, we love talking about the difference between Millennials and Gen X. Mainly because we are probably Gen Xers and we think we are better than everyone else. But we also like it because labels make things easier.
