The sign at The Burger Shack Grill, owned by Greg Coulter, reads: "Pull your pants up or don't come in," the Houston Chronicle reported Monday.
"Try to have some decency & respect for others. No one wants to see your underwear," the sign reads. "Does not apply to children under 3 years of age."
Coulter said the sign has received "100 percent" positive feedback since it was installed about three months ago.
Coulter said the sign grew from his "general disgust" for very low-hanging, or "sagging," pants.
