Sweepstakes
Who’s going to tell Boomers that most sweepstakes are a giant scam? Even if they aren’t malicious, many times you don’t end up receiving your winnings because of some loophole in the terms & conditions that nobody bothers to read. However, for some reason sweepstakes are still around and have yet to die out.
In Person Banking
Try to tell someone under the age of 30 to go to a bank to make a payment instead of using their bank’s app on their phone and see how they respond. Younger generations will do anything to avoid going to the bank in person, while Boomers are still familiar with this concept from the pre-online banking days.
