Many bar owners install purse hooks to keep bags more secure.

But how many have wired an electrical outlet and dual USB charger port at each seat?

Mike Naessens at Old City's Bierstube just went that route at his 14-seat bar.

Don't have a cable? Bierstube sells three-in-one lightning/30-pin/micro USB charging cables for $3.69.

This amenity, backed by free wifi, could be a great thing: Naessens gets to sell food, beer and booze while patrons' iPhones charge, and the "battery freaks" among us know that we'll be able to hold a charge longer.

Then again, this "Genius Bar" could also just fuel a sad aspect about our smart-phone society - patrons idly yapping or texting while charging as they ignore everything around them.
