The benefit of bringing a large, colorful sign to the airport is that it’s easy to spot. The bad thing is that it’s easy for everyone to spot. So, if you write an embarrassing message on your sign, you can bet that everyone at the airport is going to silently laugh at your message.
This is especially true if you bring a sign like this one. “Hey, sweet thang. Pucker up!” Do people still talk like this? And how many sweet thangs came over to give this guy a quick pucker before his wife or girlfriend arrived?
