“Flashing smiling subliminal images at customers waiting to be served at a burger restaurant doesn’t seem very practical, or very ethical for that matter. I think the study does show that even a tiny elevation of mood, so small that it is imperceptible to the subjects, could affect their spending. This means that the manager who trains her employees to smile is on the right track. It also suggests that imagery in the purchase area should be positive and people should be smiling.”
A smile is the best way to say “Hello, won’t you come on in. We are glad you here. You are very important to us”
Smile.
