I witnessed the same thing at a small cantina in Mexico where my buddies and me walked in with a cheap bottle of Baja red wine plonk, but the bartender there used a dishrag instead of a shoe. Worked like magic.
Are you making a reference to Justin Timberlake? And if so, are you talking about his personal life? You can't possibly be making a reference to Fred Holloway. Or, wait, wait...you don't mean Timothy Mosley...never mind, I'm going to go have a glass of manzanilla now.
