We recently purchased light up gloves for our greeters. The gloves have a battery that lights up the LED fingertips. Kids love them and it puts a smile on their face as they enter.
Since first-time guests decide if they are going to return in the first 8 minutes (you can read more about that here), anything you can do to add a "wow" factor will increase the chances of them returning.
The gloves are fairly inexpensive. You can get them on Ebay or Amazon for as low as $5-10 a pair.
What are some other fun things you do to welcome people? Share your ideas with us in the comment section below.
